@@@@Attapulgite, activated carbon and the supermicro porous polyurethane as the supporter, the three supporter load of Cu2O were prepared by liquid phase synthesis, and their photocatalytic oxidation effect was investigated by the adsorption and degradation of Rhodamine B. The results showed that when the simulated Rhodamine B dye wastewater initial concentration was 200mg/L, reaction time was 50 min, the loaded Cu2O dosage of three supporter was 11.0g/L, 9.0g/L and 5.0g/L, respectively, the removal rate of rhodamine B in the simulated wastewater were 81.64%, 87.21% and 78.46%, respectively. The removal rate of Rhodamine B was still better after five repeated use of the three catalysts.
