REACTION OF CHROMIUM(VI) WASTES WITH SUGARS

Aqueous etching wastes from the electronic industry contain heavy metal ions such as chromium(VI), chromium(III) and copper(II). In remediation of this waste, chromium(VI) should be reduced to chromium(III), and then removed via precipitation or extraction. This report describes results of chromium(...

Description
Summary:Aqueous etching wastes from the electronic industry contain heavy metal ions such as chromium(VI), chromium(III) and copper(II). In remediation of this waste, chromium(VI) should be reduced to chromium(III), and then removed via precipitation or extraction. This report describes results of chromium(VI) reduction using water-soluble sugars (sucrose and glucose) for remediation of aqueous etching wastes from this industry. In strong acid solutions (pH
