Opis:
Leaching of heavy metals (Zn, Pb, Cu, Ni and Cr) from hazardous waste originating from steel works (slag) has been investigated. Contaminant leaching behavior from monolithic waste materials in the function of time was examined. There was established the cumulative leaching of elements per surface area of waste material and the impact of the duration of the leachant contact with the waste on the leachability. The types of processes accompanying the release of heavy metals were determined as well. Surface wash-off and dissolution were dominant processes during the leaching of the analyzed elements. Chromium was the only element whose release from the sample was controlled by diffusion when subjected to leaching in a liquid of pH 7. Due to the low levels of heavy metal leaching in relation to their concentrations in the samples, it seems that longer duration of the tank test can contribute to the release of additional amounts of the heavy metals.

Opis:
The content of lead, zinc, copper, nickel and chromium in the aerial and underground parts of M. sinensis from eleven years old plantation and M. sacchariflorus and M. giganteus from nine years old plantations were analysed in order to recognize what organs of the plant play the most important function as a metal accumulator. It was found that in the aboveground parts, lead, zinc and copper were accumulated mostly in leaves and nickel and chromium in stems of the studied species. In underground plant parts, especially in roots, zinc, copper and nickel were most abundantly accumulated, while rhizomes accumulated higher amounts of lead and chromium. The content of lead, zinc and copper was definitely lower in those plant organs than their content in soil. The content of nickel and chromium, on the other hand, showed the opposite dependence. A similar capacity for uptaking trace elements from soil was observed for M. sacchariflorus and M. giganteus, while M. sinensis it was much lower, which is confirmed by the values of the bioaccumulation factors. The translocation factor for trace metals in the studied grass species indicated great translocation of lead and nickel from the roots to rhizomes, and that of zinc to aboveground parts.

Opis:
Environmental pollution by lead ($Pb^{2+}$) and zinc ($Zn^{2+}$) ions has become an important issue due to its harmful effects on human health and environment. This work aims to evaluate the application of surface modified Egyptian bentonite mineral by acid activation using $H_2SO_4$ and thermal treatment as an adsorbent to remove lead ($Pb^{2+}$) and zinc ($Zn^{2+}$) ions from aqueous solution. X-ray diffraction (XRD), Fourier Transformed Infrared Spectroscopy (FTIR) and Scanning Electron Microscope (SEM) techniques were used to investigate the modified bentonite. The impact of organic and inorganic dispersants on rheological characteristics of bentonite suspensions was investigated. Adsorption of $Pb^{2+}$ and $Zn^{2+}$ ions using modified bentonite mineral was performed with different adsorbent doses and pH values. Removal efficiencies of lead and zinc are 99.67% and 99%, respectively with adsorbent dose of 25 g/l at pH of 6.2.

Opis:
Many industries, especially mining and metallurgy, deal with solutions containing ions. In some cases, these metal ions need to be concentrated and recovered from solutions and sometimes removed from wastewater. The ion flotation method has been applied for wastewater and water treatment, recovery of precious and platinum group metals, preconcentrating of rare earth elements, selective separation of multicomponent ions from dilute solutions, and analytical chemistry. It has been employed to separate heavy metals from a liquid phase using bubble attachment, originated in mineral processing. In these cases, ion flotation has an important place among other methods because it is a cheap and practical method. In this study, many ion flotation studies, especially applied at laboratory scale, were reviewed. This method gives very successful and promising results in removing heavy metals with toxic effects from wastewater and selective separation of metal ions from very low concentrated solutions. Ion flotation may take place in industrial scale operations with the new developments in flotation machines and collectors with better selectivity, high efficiency, lower cost, and environmental friendliness.

Opis:
The marble dust as a harmful industrial waste of marble fabrication was evaluated as aneconomical and efficient green adsorbent for Acid Red-1 dye and lead ions. The XRD, XRF, particle size, surface area and zeta-potential measurements were used to characterize the marble dust. The removal efficiency was optimized by studying several parameters such as pH, temperature, contact time, adsorbent dose and initial concentration. The optimum removal was achieved at pH 6, 20°C after 60 min in the presence of 2.5g/L marble dust. The rates of adsorption were found to follow the pseudo-second-order model. The results showed better fitting to Freundlich isotherm. The thermodynamic studies revealed that the adsorption process is spontaneous, exothermic and favorable at low temperature. The free energy (∆G°), enthalpy (∆H°), and entropy (∆S°) changes were calculated to predict the nature of adsorption.The removal efficiency was improved by calcination of the marble at 700°C. Application for textilewastewater showed high removal efficiency up to 99.9%of inorganic and organic pollutants. The product of treatment was used in the concrete and bricks manufactured, so there is nogeneration of second-order pollutants.

Opis:
Silene vulgaris ecotypes Wiry and Gajków, originating from a serpentine heap and a natural site, respectively, were cultivated from seeds on two substrates. The former was a serpentine heap located in Wiry (Poland, Lower Silesia), the latter – natural soil located in Gajków (Poland, Lower Silesia). The growth of both ecotypes on the Wiry soil was strongly inhibited. The Wiry ecotype grown on the serpentine heap accumulated more macro-, micro-nutrients and heavy metals (Ni, Co, Cr) than ecotype Gajków. Enzyme pyrogallol peroxidase was more active in the leaves of the Wiry ecotype grown only on Wiry soil. Ecotype Gajków, grown on the serpentine heap, was characterized by higher non-protein thiol, total polyphenol and anthocyanin content. The results obtained in the study indicated heterogeneous responses between ecotypes, depending on the applied substrate, while parallel studies of tolerant and sensitive populations made possible the study of the taxon’s tolerance mechanisms to heavy metals.

Opis:
The impact of land use and a distance from the highway on heavy metal concentration in soils along the highway has been investigated. 28 soil samples were collected in August 2014 from the roadside soils of the Hemmat highway of Tehran, Iran. The results showed that the mean concentrations of Pb, Cr, Ni, Zn and Cd were 144, 17.20, 18.91, 86.84, 3.86 mg/kg–1, respectively. With exception for Cd, the concentrations of the heavy metals decreased upon increasing distance from the highway that shows the background amount of cadmium in the soil area was high. The values of the enrichment factor (EF) showed that Ni, Zn and Cr have a natural source (EF < 10) and Pb and Cd have an anthropogenic source (EF > 10). The anthropogenic sources are emphasized for these heavy metals, thus indicating the strong human influence. The mean values of geoaccumulation index (Igeo) for Pb, Zn, Cd were high at residential, under-construction and green space land uses. The ecological risk index (RI) for roadside soils was higher than 300, indicating that sampling sites had a considerable ecological risk. The potential ecological risk index for single metal decreases in the following sequence: Cd > Pb > Ni > Zn > Cr.

Sorption of Cd2+, Ni2+and Zn2+ions on natural (ZPCli), sodium modified (ZPCliNa) and acid modified (ZPCliH) zeolites have been investigated in function of the contact time, pH, and metal concentration by the batch technique. The characterization of ZPCIi, ZPCliNa, and ZPCliH materials was performed using X-ray powder diffraction, scanning electron microscopy and energy dispersive X-ray spectroscopy techniques. The surface area (BET) and the pHpzcwere also determined. The pH in the point of the zero charge of ZPCli, ZPCliNa, and ZPCliH zeolites was 8.25, 8.00, and 2.05, respectively. The kinetic sorption data for ZPCli, ZPCliNa and ZPCliH were well fitted to the pseudo-second order model (R2> 0.99). The linear model described the Cd, Ni and Zn sorption isotherms for ZPCliH, while for ZPCliNa and ZPCliH it was the Freundlich model. The unmodified and modified zeolitic materials showed the highest sorption capacity for Cd2+, lower for Zn2+ and Ni2+.

Opis:
Zinc(II) complexes removal from aqueous chloride and chloride-nitrate(V) solutions was realized using different type of sorbents such as an ion exchangers of the chelating type (Lewatit MonoPlus TP220, Purolite S984), strongly basic (Lewatit MonoPlus SR7, Purolite A400TL, Dowex PSR2, Dowex PSR3) and weakly basic (Purolite A830) anion exchangers as well as the adsorbent resin Lewatit AF5. The kinetic and equilibrium studies using the static method were carried out in order to examine the rate of zinc(II) removal as well as to obtain the maximum adsorption capacities. The obtained experimental data were analyzed by means of different kinetic and isotherm models as well as the corresponding parameters were calculated. The desorption and reuse studies (three cycles of sorption/desorption) were also discussed. Lewatit MonoPlus TP220 showed the highest efficiency of zinc(II) removal and the maximum sorption capacity was equal to 620 mg/g. The kinetics of zinc(II) sorption is well described by the pseudo-second order kinetic model. The interactions between the sorbent and zinc ions are strong because no quantitative zinc desorption was observed (40% using nitric(V) and sulfuric(VI) acids for Lewatit MonoPlus TP220).

Opis:
In this research, carboxymethyl chitosan-bounded Fe3O4 nanoparticles were synthesized and used for removal of Co(II) and Ni(II) ion metals from wastewater. The capability of magnetic nanoparticles for metal ions removal was investigated under different conditions namely pH, initial concentration of metal ions and adsorbent mass. The assessment of adsorbent performance for metal ions removal under different conditions requires cost and time spending. In this regard, the capability of artificial neural network (ANN) and nonlinear multi-variable regression (MNLR) models were investigated for predicting metal ions removal. The values of operational parameters such as pH, contact time, initial concentration of metal ions and adsorbent mass were applied for simulation by means of ANN and MNLR. A back propagation feed forward neural network, with one hidden layer (4:8:2), was proposed. Two criteria, including mean square error (MSE) and coefficient of determination (R2) were used to evaluate the performance of models. The results showed that two models satisfactorily predicted the adsorbed amount of metal ions from wastewater. However, the ANN model with higher R2 and lower MSE than the MNLR model had better performance for predicting the adsorbed amount of metal ions from wastewater.

The transport of heavy metals from mining disposal site to groundwater and surface water is one of the most serious environmental problems in the world. The transport of heavy metals such as Zn, Cd and Mn from leaching filter cake in RECo, Zanjan, Iran was examined by using column leaching. Parameters studied included: flow rate, pH of input solution and leaching time. In this study, the maximum dissolution percents of Zn, Cd and Mn in input solution pH of 5 were 45.50 %, 53.97% and 19.94%, respectively. To statistically analysis the experimental results, SPSS14 software was employed. The results of SPSS 14 indicated that for the Zn, Cd and Mn dissolution, time and flow rate were found respectively, the effective parameters for the pollution in zinc leach residues.

Opis:
The effect of increasing contamination with copper on the content of trace elements in soil after application of compost, bentonite and zeolite has been examined. The contents of copper, cadmium, lead, chromium, zinc, nickel, manganese, iron and cobalt were determined in soil. Soil contamination with copper and the application of neutralizing substances (compost, bentonite and zeolite) had significant effects on the contents of trace elements in soil. Copper pollution mainly caused a very high increase in the content of copper and a smaller one in the amount of cadmium in soil. Copper contamination caused a decrease in the content of cobalt, nickel, zinc, manganese, iron and lead in soil. All of applied substances, especially zeolite, reduced the content of copper, as well as cadmium, chromium and, to a smaller extent, lead and manganese in soil. It is worth noticing that the effect of zeolite was much stronger than the effect of bentonite or compost. Compost acted similarly with respect to cobalt and nickel. Zeolite had a similar effect on the content of zinc and iron in soil. Bentonite had a comparable influence on the accumulation of zinc in the soil. In turn, bentonite and zeolite contributed to an increase in the content of nickel and cobalt in the soil.

Opis:
Phytochelatins (PCs) exist widely in plants and are closely related to plant resistance to heavy metals (HMs). Glutathione (GSH) and nonprotein thiols (NPTs) are the major components of PCs. This study investigates the role of the PCs of Cladophora rupestris in Pb2+ accumulation and detoxification. The distribution of Pb2+ in the PCs of C. rupestris was studied. FTIR and XPS are used to characterize the chelating power of Pb2+ with PCs in C.rupestris. The curve fitting of the secondary protein structure is used to identify the functional groups with Pb2+. Results showed that the content of Pb2+ in the PCs of C. rupestris increased with an increase in Pb2+ stress. Pb content increased to 352 and 314 mg/kg in NPTs and GSH, respectively, when Pb stress concentration reached 7.5 mg/dm3 . The Pb2+ fraction of C. rupestris PCs reached a maximum of 10.8 and 9.3% in NPTs and GSH, respectively. The Pb2+ uptake by GSH and NPTs was 40–48% and 52–60%, respectively. Pb2+ bound with the PCs of C. rupestris, forming complexes that contained Pb–OOC, Pb–C=O, CO–Pb, –N=Pb, Pb–NH2, Pb–O, Pb–N–, Pb–C–, Pb–S, and Pb2+ with multiple groups of PCs as bridging ligand atoms.

Opis:
The presence of heavy metals, e.g. Cu in groundwater as a result of acid mine drainage (AMD) poses a threat to the environment. In order to remove cationic copper from solutions simulating the AMD, iron reactors were applied as zero-valent iron. The precipitates formed on the surface of the reactors and their specific surface area were determined. Affinity of copper in ionic form with reactors was investigated. The results show that for iron reactor immersed in solution of initial pH 3, copper oxides as well as iron oxides and carbonates (to lower extent) were formed. More reaction products were generated in case of higher pH (initial pH = 6). These were mainly: copper and iron oxides, Cu0, and probably iron sulfates and carbonates. These precipitates caused an increase in specific surface of the reactors. In both cases (mainly for the reactor immersed in a solution of lower pH) the surface of the reactors was not covered entirely with a coating. The sorption study indicated that copper ions may be retained on the surface of reactors only at higher pH, because the pH at point of zero charge of iron reactors was ca. 6.2.

Opis:
Short-term biotests were used to determine the effectiveness of the use of compost and fly ash in the stabilization of heavy metals in contaminated soil. For this purpose, in two independent experiments, either compost (3:1) or fly ash (1:1) were added to soil contaminated with heavy metals. To assess seed germination and root elongation of Sorghum saccharatum L., Lepidium sativum L., Sinapis alba L. after three days a Phytotoxkit test was used. Seedling emergence and biomass yield after 21 days were evaluated. Obtained data indicate better practical applicability of the seedling emergence test thanks to the longer duration resulting in more reliable conclusions provided in that test. A short, 3-day test did not confirm any effective stabilizing role of theapplied additives. Sorghum saccharatum L. turned out to be most sensitive to the altered soil conditions, while Lepidium sativum L. was most tolerant.
