摘要
采用沉淀-浸渍法制备SO24-/Fe2O3固体超强酸催化剂。通过单因素实验考察了SO24-/Fe2O3光降解甲基橙的效果。结果表明,固体超强酸SO24-/Fe2O3光催化降解甲基橙的最优反应条件是:溶液pH值为6,催化用量2g.L-1,甲基橙溶液初始浓度10mg.L-1,反应时间90min。在最优反应条件下,甲基橙的降解率可达90%以上。
The SO /Fe2O3 solid superacid catalyst was prepared by chemical precipitating and soaking method,and the effect of photocatalytic degradation to methyl orange was studied with the single-factor experiment method.The results showed that when the catalyst quantity is 2g·L-1,pH value is 6,the first concentration of methyl orange is 10mg·L-1 and reactive time is 90min,the degradation ratio of methyl orange is over 90%.
