摘　　要：采用新型燃烧剂抗坏血酸,以高锰酸钾和硝酸铁为原料,燃烧法制备轻质蓬松铁酸锰复合氧化物,考察复合物的类型、催化剂的用量、溶液的酸碱性、双氧水用量等条件对亚甲基蓝光催化性能的影响。结果表明,最佳光催化条件为:催化剂为铁锰摩尔比1:1的复合氧化物、催化剂用量为0.01 g/L,pH=6,双氧水用量为60 mL/L。在无光的辅助下,复合氧化物可将亚甲基蓝脱色91%,还对重金属具有吸附作用。Ascorbic acid as a new combustion agent,potassium permanganate and nickel nitrate as raw materials,composite oxides of manganese ferrite were prepared by combustion. The effect of the composite type,amount of catalyst,the pH of the solution,the amount of hydrogen peroxide on the photocatalysis performance of methylene. The result showed that the optimal photocatalytic conditions is that molar ratio of potassium permanganate and nickel nitrate is 1：1,dose of catalyst is 0. 01 g/L,pH was 6,the amount of hydrogen peroxide is 60 mL/L. The composite decolorized 91% of methylene blue without irradiation of light. Moreover,the composite absorb heavy metal too.
