Opis:: The dialysis of metal ions including Mg(II), Ni(II) and Zn(II) through ultrafiltration membranes made of polysulfone and sulfonated polysulfone was enhanced by sodium salt of poly(acrylic acid) diluted in the receiving compartment. In experiments, concentration of Mg(II), Ni(II) and Zn(II) in the feed solution was equal to 10-3 mol/dm3, concentration of polymer in the receiving solution was equal to 10-2 mol/dm3, and pH = 9. In the presence of complexing polymer, concentration of all metal ions in the receiving solution is higher than 50% for the polysulfone membrane and increases to almost 100% for the sulfonated polysulfone membrane. This effect is due to a cation-exchange property of the sulfonated polysulfone membrane.

Opis:: This paper presents the development of mathematical models for positive and negative azeotropes in the range of the more volatile concentrations component: x∈[0; az] ∨ [az; 1]. The coefficients of these models, which, on their basis, were determined the relative volatility of α and the azeotrope concentration az, defined with the high accuracy (R2∈[0,926; 0,999]) and presented them to the table for all subjects of distillation systems. Based on these relationships, the integration of the mass balance equations of the distillation differential process d(Sx)=ydS was carried out and determined the dependence of the distillate obtained from 1 mole of pig iron D/S0 from the α, az coefficients and xw, xs concentrations. Based on these dependencies, charts D/S0 were prepared from predefined by the authors parameter t=[0,05; 0,25; 0,5; 0,75] which is the change in the concentration of pig iron in the process of concentration. Dependencies, presented for distillation balances of positive and negative azeotrope, in the tested ranges, for similar values of α, have the same mileage. The calculations were made for the 126 distillation systems.

Opis:: A vast array of colorants used in various industries include metal complex colorants, which are useful mainly in the textile industry. Substances to be used in fiber dyeing are expected to have optimum properties, therefore, such compounds remain to be of interest to researchers. The results of studies on the possible modifications of known colorants are presented in this paper.
