Сорбенты на основе растительных материалов для очистки хромсодержащих сточных вод

Abstract

Sorbents based on cellulose-containing materials (cellulose, wood, rotted straw) for various tertiary treatment were obtained by chemical modification of phosphorylating solutions. The optimum composition of the modified solution, the main components of which are nitrogen- and phosphorus-containing substances, is established. The degree of phosphorylation and exchange capacity of chromic ions is determined for various sorbents.
