SORBENT FOR HEAVY METALS, METHOD OF ITS PRODUCTION AND METHOD OF WATER PURIFICATION Russian patent published in 2008 - IPC B01J20/08 B01J20/32 B82B1/00

Abstract RU 2336946 C2

FIELD: chemistry.

SUBSTANCE: claimed is sorbent, made in form of granules of highly-porous aluminium oxide with pore volume not less than 0.55 cm³/g, specific surface not less than 200 m²/g, representing assembly of nanofibres, connected together into rigid spongy structure and containing nano-sized particles of iron oxides, formed as layer on the surface of said granules in amount 2-10% from granules weight. Sorbent is obtained by impregnation of porous base with solution of iron compounds with further processing with alkali.

EFFECT: sorbent has high capacity and mechanical strength.

17 cl, 2 ex, 2 dwg
