光催化降解甲基橙的研究

采用TiO2为催化剂,研究了光催化降解甲基橙的影响因素。结果表明:紫外光是比较有效的辐射光源;甲基橙溶液质量浓度为6 mg/L、TiO2加入量为0.5 g/L、pH值为2时,甲基橙降解率最大;添加少量的Fe3 可提高甲基橙的降解率,其最佳投加量为0.1 mmol/L。利用光催化降解有机染料废水具有广阔的发展前景。

Study on Photocatalytic Degradation Methyl Orange

Photocatalytic degradation Methyl Orange by catalyst TiO2 was investigated.The results indicated that,the ultraviolet ray was the effective radiation photosource;When the concentration of the Methyl Orange was 6 mg/L,the concentration of TiO2 was 200 mg/L,the degradation rate was the highest in pH 2. Added Fe3 could enhance to the degeneration rate of the Methyl Orange,the suitable concentration was 0.1 mmol/L.It had expansive developmental foreground that studying on photocatalytic degradation wastewater of organic dye.
