METHOD OF INCREASE OF SORPTION ACTIVITY OF ZEOLITE-CONTAINING ROCK

摘要

FIELD: medicine, industrial sanitation and hygiene. SUBSTANCE: method of increase of sorption activity of zeolite-containing rock involves reduction of clinoptilolite size to grains with diameter of 0.5-1.0 mm, elutriation, preparation of aqueous suspension of enriched rock, action with electric current in the course of 10.0 h with periodic mixing and removal of liquid over precipitate with subsequent dehydration of obtained product. Method makes it possible to increase degree of sorption extraction from bioliquids by 22.0 of boric acid; by 11.0-15.0 % of copper; by 30.0 % of zinc; by 45.0 % of cadmium by 53.0 % of lead as compared with natural form of sorbent. EFFECT: increased degree of sorption extraction of various elements from bioliquids. 1 tbl
