摘　　要：以尿素和硝酸铜为原料,采用煅烧方法制备了非均相Fenton催化剂的Cu-C_(3)N_(4),研究了催化剂用量、反应系统、pH、光源强度对罗丹明B(RhB)降解的影响。结果表明,最佳材料Cu-CN-3用量为1 g/L,RhB浓度为50 mg/L,H_(2)O_(2)浓度为0.01 mol/L,Cu-C_(3)N_(4)/H_(2)O_(2)+PC耦合体系,中碱性条件,50 W可见光下,罗丹明B 16 min的去除率可达99.7%。4次循环实验,降解效率几乎保持不变。The heterogeneous Fenton catalyst Cu-C_(3)N_(4)was synthesized by the calcination method,and the effects of different ratios of catalysts,different systems,pH,and light source intensity on the degradation of Rhodamine B(RhB)were studied.The results showed that the catalyst was 1 g/L and the RhB concentration was 50 mg/L,H_(2)O_(2)concentration is 0.01 mol/L,the best material Cu-CN-3,Cu-C_(3)N_(4)/H_(2)O_(2)+PC systems,·OH can be neutral and alkaline conditions,a light source intensity of 50 W,the removal rate of Rhodamine B can reach 99.7%in 16 min.In the recyclability experiment test of 4 cycles,the available material performance is good,and the degradation effeciency remains almost constant.
