Влияние степени сшивки N-2-сульфоэтилхитозана на его динамическую емкость по гидроксид-ионам

Abstract

In this work dynamic exchange capacity of cross-linked N-2-sulfoethylchitosan was determined by the method of acid-base reverse potentiometric titration. It was found that dynamic exchange capacity for OH- ions increased with the increase of cross-linking degree. Swelling curves of N-2-sulfoethylchitosans with cross-linking degrees of 15, 30 and 50% were obtained. It was confirmed that sorbent's degree of swelling decreased with the increase of cross-linking degree.
