Extraction of cesium from aqueous media by solution of 25,27-bis (1-octyloxy)calix[4]arene-crown-6 (calix[4]arene-crown-6, DOCC-1) in dichloromethane is investigated. A study of sorption properties of silica xerogel with additives of calix [4] arene-crown-6 and tributyl phosphate is performed. The optimal conditions for surface modification of "enterosgelum (hydrogel of methylsilicic acid) and natural zeolite mordenite by calixarenes DOCC-1, which is selective to cesium are found. A simple method for the synthesis of particles of titanium dioxide as a promising carrier for immobilization of calixarene derivatives is developed. Product Description popup.authors Бєліков К.М.
