METHOD OF PRODUCING LEAD SULPHIDE-BASED COMPOSITE SORBENT Russian patent published in 2013 - IPC B01J20/02 B01J20/22 B01J20/32

Abstract RU 2488439 C1

FIELD: chemistry.

SUBSTANCE: invention relates to techniques of producing sorbents for extracting silver from waste water and process solutions. The sorbent is obtained using a dispersion of fibrillated cellulose fibres as lead sulphide carriers. Lead sulphide is precipitated with sodium sulphide in an aqueous dispersion which contains lead acetate or nitrate and said fibres. A sorbent containing 50-300 pts.wt lead sulphide per 100 pts.wt fibre is obtained.

EFFECT: invention enables to obtain a sorbent with capacity of 300-675 mg silver per 1 g sorbent.
