| 摘 要： | 用酸性红3R染料溶液模拟染料废水,在可见光强度为91 700μW/cm2,紫外线强度为499μW/cm2的太阳光照射下,研究了自制纳米TiO2/硅藻土复合材料的光催化性能。同时探讨了体系pH、光照时间以及染料初始浓度对光催化效果的影响。实验结果为:当体系溶液pH=3时,光照时间越长,染料初始浓度越低,光催化效果越好。

| Abstract: | The photocatalytic properties of homemade nanosized TiO2/ diatomite composites are studied with acid red 3R as waste water under solar light irradiation which visible light intensity is 91700uw/cm2 and ultraviolet strength is 499 uw/cm2, and the effect of pH, illumination time, and on catalytic performance were also investigated in detail. Results indicate that the photocatalytic activity of composite exhibits excellent when pH is 3, the illumination time is longer, and initial concentration of dye is lower. |
