Removal of Cr3+ ions by phytic acid derivatives from rice bran

Abstract

The process of removing chromium(III) ions from aqueous solutions was investigated with respect to a phosphorus-containing product containing inositol hexaphosphoric acid derivatives obtained from rice bran-rice waste products of Far Eastern breeding varieties. The removal efficiency of chromium(III) ions by phosphorus-containing product depended on their initial concentration and reached 82%. Thus, environmentally friendly polyfunctional chelate materials from rice production wastes could be used to remove metal ions from aqueous solutions.
