Abstract
Ion exchange materials are successfully used for solution of a number of practical problems, such as production processes waste-free technology creation, industrial wastewater treatment, rational natural resources and environmental protection use. The Physicochemical and sorption characteristics study is needed for the determination of ion exchangers application promising areas, however chemical research methods are laborious, and atomic absorption spectroscopy is not always available. The purpose of this work is to find and use available methods, which do not require complex technological equipment for metal ions concentration determining in the solutions. Methodology. Stripping voltammetric determination of metal ions by addition method has been used to determine the equilibrium concentrations of metal ions in the solutions. Results and discussion. The non-ferrous metal ions concentration determining methods have been developed and used on the voltammetric analyzer «Ecotest BA», which is a real economical alternative to expensive methods of analysis. Stripping voltammograms of samples, which contain cadmium and copper, zinc, lead cations; vanadate ion, molybdate ion were constructed. The ions concentrations in the equilibrium solutions after sorption are calculated. Conclusion. The stripping voltammetric method is convenient for studying the sorption and ion-exchange materials complexing properties; it and also allows to determine several metals without their preliminary separation resorting.
