摘要
本文采用静电自组装法成功制备了三元复合材料K_(8)[Mn(H_(2)O)CrW_(11)O_(39)]/PANI/SnO_(2),并使用UV-vis、XRD、XPS、FT-IR、SEM-EDS和N_(2)吸附-脱附等手段对其进行表征。并且通过光催化降解刚果红染料的实验,确定了反应的最佳条件为:刚果红溶液的初始浓度为10 mg·L^(-1),初始pH值为2,催化剂用量为0.002 g时,溶液脱色率可达98.1%。重复回收三次后,溶液脱色率仍达到88.1%。
The ternary composite K_(8)[Mn(H_(2)O)CrW_(11)O_(39)]/PANI/SnO_(2)was successfully prepared by electrostatic self-assembly method,it was characterized by UV Vis,XRD,XPS,FT-IR,SEM-EDS and N_(2)adsorption desorption.The results showed that the best reaction conditions were as follows:When the initial concentration of Congo red solution is 10 mg·L^(-1),the initial pH value is 2,and the amount of catalyst is 0.002 g,the decolorization rate of Congo red solution can reach 98.1%.After repeated recovery for three times,the decolorization rate of the solution still reaches 88.1%.
