METHOD OF RECOVERING METAL IONS FROM SOLUTIONS Russian patent published in 2004 - IPC

Abstract RU 2221752 C1

FIELD: waste water treatment. SUBSTANCE: invention relates to methods of cleaning waste waters and can be used in chemical and metallurgical industries when cleaning waste waters to remove copper, nickel, cobalt, mercury. And chromium ions. Invention consists in adsorption of metal ions from solutions with pH 7 to 10.5 on cationite based on modified rubber crumb, which is, more particularly, product obtained from interaction of sulfurized (11-67% sulfur) rubber crumb with sodium hydroxide aqueous solution at weight ratio 1:(0.38-1.7). EFFECT: increased sorption capacity of sorbent and enabled sorption of chromium ions. 2 tbl, 3 ex
