Opis:
In this work, separation of cobalt(II) over lithium(I) ions from aqueous chloride solutions by synergistic solvent extraction (SX) has been studied. A synergistic mixture of commercial extractants such as bis(2,4,4-trimethylpentyl)phosphinic acid (Cyanex 272) and tributyl phosphate (TBP) in kerosene was used as a selective extractant. The investigations were first performed to select optimal conditions for the effective separation including pH of the aqueous phase as well as concentration of synergistic mixture. High selective solvent extraction of cobalt(II) over lithium(I) from chloride solution has been achieved by the mixture of 0.1 M Cyanex 272 and 0.05 M TBP in kerosene while efficient Co(II) stripping has been performed by 0.5 M sulphuric acid.

Opis:
In this work the selective transport of cobalt(II) and lithium(I) ions from aqueous chloride solutions through polymer inclusion membranes (PIMs) is presented. Triisooctylamine (TIOA) has been applied as the ion carrier in membrane. The effects of various parameters on the transport of Co(II) and Li(I) were studied. The obtained results show that Co(II) ions were effectively removed from source phase through PIM containing 32 wt.% TIOA, 22 wt.% CTA (cellulose triacetate) and 46 wt.% ONPOE (o-nitrophenyl octyl ether) or ONPPE (o-nitrophenyl pentyl ether) into deionized water as the receiving phase. The results indicate that there is a possibility of polymer inclusion membranes application to recover Co(II) and Li(I) from aqueous chloride solutions.

Opis:
This paper presents study on the facilitated transport of cadmium(II), cobalt(II) and nickel(II) ions from aqueous chloride solutions through polymer inclusion membranes (PIMs) with phosphonium ionic liquid. Cyphos IL 101 (trihexyl(tetradecyl) phosphonium chloride) was used as a selective carrier for synthesis of cellulose triacetate membranes containing o-nitrophenyl pentyl ether (ONPPE) as a plasticizer. Effect of different parameters such as hydrochloric acid concentration in the source phase as well as ion carrier concentration in the polymer membrane on metal ions transport has been investigated. Cd(II) was transported preferably from hydrochloric acid solutions containing Co(II) and Ni(II) through PIM containing 18.8 wt.% CTA and 26.0 wt.% Cyphos 101 and 55.1 wt.% ONPPE into 0.5 M HNO3 as the receiving phase. The obtained results suggest that there is a possibility of application of this membrane with Cyphos IL 101 as ion carrier for separation of Cd(II) over Co(II) and Ni(II) from hydrochloric acid solutions.
Przeprowadzono badania transportu jonów Cd(II), Ni(II) i Co(II) z wodnych roztworów kwasu solnego przez polimerowe membrany inkluzyjne (PIMs) zawierające fosfoniową ciecz jonową – Cyphos IL 101 (chlorek triheksylo(tetradecylo) fosfoniowy) w roli selektywnego przenośnika jonowego. Rolę polimerowej matrycy w membranie pełnił trioctan celulozy (CTA). Jako plastyfikatora użyto eteru nitrofenylopentylowego (ONPPE). W wyniku badań określono wpływ różnych czynników, takich jak stężenie kwasu solnego w fazie zasilającej, jak również stężenie przenośnika w polimerowej membranie na selektywność i efektywność transportu badanych jonów metali. Jony kadmu(II) były selektywnie transportowane z roztworów kwasu solnego zawierającego jony niklu(II) i kobaltu(II) do 0,5 M roztworu kwasu azotowego(V). Uzyskane wyniki wskazują, że istnieje możliwość zastosowania procesów transportu przez polimerowe membrany inkluzyjne z cieczą jonową w roli selektywnego przenośnika do rozdzielania jonów Cd(II) od Ni(II) i Co(II) z roztworów kwasu solnego.

In this work the efficient recovery of palladium(II) ions from hydrochloric acid solutions by transport through polymer inclusion membranes (PIMs) was studied. The membrane consisted of cellulose triacetate (CTA) as the polymeric support, o-nitrophenyl octyl ether (ONPOE) as the plasticizer and Cyanex 471X (triisobutylphosphine sulphide) as the ion carrier. The effect of various parameters on the transport kinetics and the recovery factor of palladium(II) was studied, including concentration of Cyanex 471X in the membrane, hydrochloric acid concentration in the source phase and potassium thiocyanate (KSCN) concentration in the receiving phase.

In this work a selective transport of Co(II) and Li(I) ions from acidic chloride solutions through polymer inclusion membranes (PIMs) with Cyanex 301 has been studied. The effect of composition of the polymer membrane has been investigated. The obtained results show that around 98% of Co(II) was transported from the source phase containing 0.01 M Co(II) and 0.01 M Li(I) at pH 4.0 through PIM after 12 h into 3.0 M HCl. The membrane containing 18 wt.% cellulose triacetate (CTA), 32 wt.% Cyanex 301 and 50 wt.% o-nitrophenyl octyl ether (ONPOE) showed very good stability, suggesting that there is a possibility of application of the membrane for Co(II) recovery from acidic leach liquor solutions of spent lithium ion batteries (LIBs).

Opis:
The growing industrial application of rare earth metals led to great interest in the new technologies for the recycling and recovery of REEs from diverse sources. This work reviews the various methods for the recycling of spent fluorescent lamps. The spent fluorescent lamps are potential source of important rare earth elements (REEs) such as: yttrium, terbium, europium, lanthanum and cerium. The characteristics of REEs properties and construction of typical fluorescent lamps is described. The work compares also current technologies which can be utilized for an efficient recovery of REEs from phosphors powders coming from spent fluorescent lamps. The work is especially focused on the hydrometallurgical and pyrometallurgical processes. It was concluded that hydrometallurgical processes are especially useful for the recovery of REEs from spent fluorescent lamps. Moreover, the methods used for recycling of REEs are identical or very similar to those utilized for the raw ores processing.

Opis:
An experimental investigation concerns zinc(II), cobalt(II), nickel(II), copper(II) and cadmium(II) ions separation from aqueous chloride solutions by solvent extraction and transport through polymer inclusion membrane (PIM) processes. The selective transport of metal ions from the aqueous chloride source phase through PIM containing cellulose triacetate (support), o-nitrophenyl pentyl ether (plasticizer) and di(2-ethylhexyl)phosphoric acid (ion carrier) is shown. Zn(II) can be effectively removed from dilute aqueous chloride solutions by its transport through PIMs with di(2-ethylhexyl)phosphoric acid as the ionic carriers into 1.0 M HCl as the receiving phase. The transport selectivity of Zn(II) over Co(II), Ni(II), Cu(II) and Cd(II) decreases while the pH of the solution increases in the source phase. Also, by solvent extraction, Zn(II) can be selectively removed from dilute aqueous chloride solutions.

Opis:
The separation of manganese(II) and nickel(II) from chloride solution with di-(2-ethylhexyl) phosphoric acid (D2EHPA) was studied. The metal ions were separated using solvent extraction and transport through polymer inclusion membranes (PIMs) with D2EHPA as the extractant/ion carrier. The aqueous solutions consisted of 0.010 M manganese(II) and nickel(II) chlorides. The influence of aqueous phase pH on the separation of Mn(II) and Ni(II) has been investigated. Mn(II) can be selectively removed from chloride solution at equilibrium pH equal to 2.90. From the organic phase, Mn(II) was stripped with 0.1-2.0 M aqueous solutions of HCl, H2SO4 and HNO3. The competitive transport of Mn(II) and Ni(II) through PIMs was studied as a function of the ion carrier and plasticizer concentration in the membrane.
