摘　　要：采用浸渍法将Waugh结构钼锰杂多化合物负载于层析硅胶,制备了负载型催化剂并对其结构进行了表征.对罗丹明B进行光催化降解实验研究,结果表明:在自然光照条件下,罗丹明B初始浓度为15.00 mg·L^(-1),催化剂投加量为2.0 g·L^(-1),初始pH为2.5,反应时间为120 min时,脱色率可达到99.67%,催化活性良好,且催化剂重复使用6次脱色率仍可达到69%以上.The supported catalyst was prepared by impregnation method,via supporting molybdenum-manganese heteropoly compound with Waugh Structure onto the chromatographic silica gel and its structure was characterized.The photocatalytic degradation experiments of Rhodamine-B showed:under natural light,the initial concentration of Rhodamine-B was 15.00 mg·L^(-1),the dosage of catalyst was 2.0 g·L^(-1),the initial pH was 2.5,photocatalytic time was 120 min,the decolorization rate was 99.67%,and the catalytic activity was good.After 6 times of repeated use,and the decolorization rate could still reach more than 69%.
