摘　　要：制备了α-SiW11Cu/PANI/SnO2光催化剂,研究了其对刚果红溶液的降解性能。结果表明:刚果红初始质量浓度为15mg/L,溶液pH为1,催化剂用量为30 mg/L,在30 W紫外灯照射下,降解时间为200 min时,脱色率可达81.78%。光催化降解刚果红过程符合一级动力学方程,反应速率常数为0.008 80 min-1。The photocatalystα-SiW11Cu/PANI/SnO2 was prepared and its photocatalytic activity for the degradation of congo red was evaluated.Experimental results showed that the decoloration efficiency of con-go red achieved 81.78%when the initial mass concentration of congo red was 15 mg/L,the simulating solu-tion was kept at pH 1 and treated by 30 W ultraviolet light using 30 mg/L ofα-SiW11Cu/PANI/SnO2 as catalyst.The kinetics of the photodegradation of congo red conformed to the pseudo-first-order equation,with reac-tion rate constant of 0.008 80 min^-1.
