Изучение сорбции ионов цинка из растворов ZnSO4-H2SO4-Na2SO4-H2O на катионите КУ-2x8

Abstract

The sorbtion processes of zinc ions on H*- and Na*-forms of KY-2x8 cation-exchange resin both in static and dynamic regimes from the solutions, containing ZnSO4, H2SO4, Na2SO4 with initial concentrations 0,02-0,15, 0,2-2, 2-6 grams per liter respectively are delt with. It has been shown that degree of the extraction of zinc ions from the solution in static regime is little dependent on the composition of the solution and the form of ion-exchange resin. The conclusion has been made that H*- or mixed H*, Na*-forms of ion-exchange resin are more preferable ones for purefication of sewige in dynamic regime, especially in those cases, when the initial concentration of zinc ions is small and that of sodium ions is high
