Separation and concentration of nonferrous and less-common metals on polyacrylonitrile sorbents in voltammetric analysis of aqueous solutions

Abstract

Fibrous materials based on polyacrylonitrile were studied as filters for separation of interfering components and for selective concentration of monitored substances in voltammetric analysis of aqueous solutions. Methods of sample preparation developed in our work may be useful in ecomonitoring of aqueous objects in the area of impact of nonferrous metallurgical plants and electroplating manufactures
