Tannery Wastewater Treatment, Picking and Galvanic Production from Chromium Ions by Sorption on the Anion Exchange Resin of the Brand AMP and Mixture of Anion Exchange Resin of the Brand AMP and Cation Exchange Resin of the Brand KU-2

Abstract

There was investigated extracting of chromium ions from an aqueous salt solution Cr2 (SO4)3 and K2Cr2O7 and mixtures thereof. Using sorption on anion exchange resin of the brand AMP from solutions of salts mixtures Cr(III) and Cr(IV) with total chromium concentration of 500 mg/dm3 can be selectively extracted anions Cr(VI) for 20 – 30 minutes. Sorption by mixture of cation exchange resin KU-2 and anion exchange resin AMP improves the extraction of salts mixtures Cr(III), Cr(IV) with a substantial reduction of sorption time.
