Динамическое концентрирование ионов меди(II) и серебра(I) N-2-сульфоэтилхитозанами со степенью модифицирования 0.7: влияние степени сшивки

Abstract

N-(2-sulfoethyl) chitosan cross-linked by glutaraldehyde is an advanced material for selective sorption of copper(II) and silver(I) ions from multicomponent solutions. This report presents the study of dependence of degree of cross-linking by glutaraldehyde on selectivity characteristics of N-(2-sulfoethyl) chitosan with substitution degree of 0.7 in dynamic conditions. It was shown that selectivity of sorption of Ag(I) ions over Cu(II) ions increased with the increase of cross-linking degree.
