不同光源下累托石-TiO2降解染料废水

以TiCl4和累托石为主要原料制备了累托石-TiO2光催化剂，研究了在紫外光和太阳光下，其降解甲基橙溶液的光催化性能．实验结果表明：在紫外灯光下反应30min，分别以TiO2和累托石-TiO2为催化剂降解甲基橙溶液，甲基橙脱色率分别为50%和93％．催化剂在相同的制备条件下，累托石-TiO2的光催化活性约为TiO2的两倍；在太阳光下，分别以TiO2和累托石-TiO2为催化剂降解甲基橙溶液6h，甲基橙的脱色率分别为62．9％和87．6％．

Degradation of Dye Waste Water by Rectorite-TiO2 under Different Lights

A photocatalyst rectorite-TiO_2 was prepared with main material of titanium tetrachloride and rectorite and used for degradation of methyl orange solution under UV light and solar light.The results indicated that the color removal of methyl orange reached 50% and 93% respectively by TiO_2 and rectorite-TiO_2 photocatalytic degradation of methyl orange solution under UV light for 30 min.The photocatalytic activity of rectorite-TiO_2 was almost as two times as that of TiO_2 under the same condition of preparation of catalyst.The methyl orange decolorization reached 62.9% and 87.6% respectively by TiO_2 and rectorite-TiO_2 photocatalytic degradation of methyl orange solution under solar light for 6 h.
