The Catalytic Properties of Copper Catalysts Prepared by Coprecipitation Method

Abstract

A series of copper catalysts were prepared by coprecipitation method and used for treating the Acid Red B wastewater with catalytic wet air oxidation method. Various parameters which influence the activity the catalyst in the process were optimized. Results showed that when (NH4)2CO3 was used as precipitating agent, and the concentration was 0.8mol / L, precipitation temperature was 40 °C, calcination temperature was 600 °C, the copper catalysts prepared by direct addition method showed better activity in treating the wastewater.
