APPLICATION OF MODIFIED SORBENTS BASED ON POLYACRYLONITRILE FIBER IN THE PURIFICATION OF NATURAL WATERS FROM COPPER IONS

Abstract

This article presents the methods of analysis that are suitable for use in stationary laboratory conditions, even at the sampling site. Such methods should be accompanied by high sensitivity and selectivity, simplicity and cheapness. Determination of the amount of the following substances, as a rule, their properties related to the concentration of extraction or the phases of ion exchange, etc., is revealed.
