采用负载型催化剂Cu2O/TiO2，以太阳光为光源，研究了其对可溶性染料罗丹明B的降解情况。主要考察了催化剂投加量，H2O2投加体积分数，溶液的酸度和反应物初始浓度等条件对罗丹明B催化降解过程的影响，从而研究催化降解的工艺条件。结果表明：Cu2O/TiO2对罗丹明B有较好的降解效果，其最佳工艺条件为：催化剂用量为1g/L，H2O2投加体积分数为1.5%，pH为5~7。此条件下，10 min就能使5 mg/L的罗丹明B溶液达到96%的降解率。

The photocatalytic degradation of soluble dye Rhodamine B by using Cu2O/TiO2 as supported catalyst and sunlight as light source has been studied. The effects of the conditions ,such as concentration of catalyst ,concentra-tion of H2O2,acidity of solution,initial concentration of reactants on the course of photocatalytic degradation of Rho-damine B are mainly investigated,so as to study the technological conditions of photocatalytic degradation. The re-sults show that Cu2O/TiO2 has pretty good degradation effect on Rhodamine B . The optimal conditions are as follows:concentration of catalyst is 1 g/L,concentration of H2O2 1.5%(volume ratio),pH 5-7. Under these condi-tions,it takes only 10 min for 5 mg/L of Rhodamine B solution to reach the degradation rate 96%.
