METHOD OF REMOVING HEAVY METALS FROM WASTE WATER BY ADSORPTION, FILTER MATERIAL (SORBENT) AND METHOD OF PRODUCING SORBENT Russian patent published in 2014 - IPC B01J20/18 B01J20/22 B01J20/30 C02F1/28

Abstract RU 2524111 C2

FIELD: chemistry.

SUBSTANCE: invention relates to industrial waste water treatment. Modified natural zeolite is used for treatment. The natural zeolite is modified with a solution of hexamethyldisilazane in toluene. The modified zeolite is dried successively in open air and in a muffle furnace at temperature of 110°C.

EFFECT: invention enables to obtain modified zeolite having zinc sorption capacity of 95 mg/g and nickel sorption capacity of 94 mg/g.
