Morphology analysis of hexavalent chromium reduction to trivalent chromium with syrup under different pH conditions

Morphology analysis of hexavalent chromium reduction to trivalent chromium with syrup under different pH conditions

Abstract Batch experiments were designed to ascertain the morphology and valence of chromium in the reduction of hexavalent chromium with syrup under different pH conditions. Results indicated that the syrup reduced hexavalent chromium to trivalent chromium, and the existing forms of Cr were mainly...
