METHOD OF PRODUCING CLAY MINERAL-BASED SORBENTS FOR HEAVY METALS AND OTHER POLLUTANTS Russian patent published in 1997 - IPC

Abstract RU 2096081 C1

FIELD: sorbents. SUBSTANCE: method involving treating sediments, e.g. aluminosilicate minerals, is distinguished by treating aluminosilicate mineral with acidic reagent for 0.5-1 h, whereupon mineral is neutralized with alkali reagent to attain pH 12- 14 and simultaneously peptizing agents are added, the two treatment stages are performed at ambient or elevated (up to 150 C) temperatures and pressure up to 5 gage atm. EFFECT: enhanced efficiency of process. 9 cl
