Abstract

Cuprous oxide catalyst was prepared and applied as photocatalist to treat chromium (VI) in wastewater, and the photocatalytic activity of the cuprous oxide was studied. The optimal conditions for the treatment was as follows: the pH of wastewater was 3, the amount of catalysts was 0.3 g/L, the reaction temperature was 60°C. Under the optimal conditions, the removal rate of chromium (IV) in wastewater reached 50% in the presence of cuprous oxide catalyst.
