【摘要】 制备了纳米TiO2/粘土复合光催化剂,其降解甲基橙效果比较显著,研究表明:在pH=2,甲基橙浓度为20mg/L,催化剂使用量为5g/L时对甲基橙有最好的降解效果,其平均回收率达到92%,有助于进一步探索提高光催化氧化反应效率的方法与途径,对实际的废水处理也有很好的指导意义。更多还原

【Abstract】 The nano titanium dioxide composite produced by us can degrade methyl orange effectively.Through the research of influencing factors,we know that TiO₂ shows the optimum degradation effect when pH is 2,the concentration of methyl orange is 20 mg/L and the addition of photocatalyst is 5 g/L.These results help us to find the way to improve the efficiency of the photocatalytic reactions.更多还原
