| 摘 要： | 采用电气石负载TiO2可见响应光催化功能材料,以甲基橙为降解脱色对象,考查了不同电气石加入量、催化剂质量、pH以及甲基橙浓度对光催化活性的影响。实验结果表明:电气石的加入有利于TiO2光催化活性的提高,其中电气石掺杂量为1%为最佳比例;催化剂加入量的增加有助于甲基橙的降解;在催化剂质量为0.2 g的条件下,甲基橙浓度为40 mg.L-1光催化降解甲基橙的效果最好。

| Abstract: | This paper is to introduce an experiment of influences of different amounts of tourmalines, qualities of catalyzers, pH and methyl orange on photo -catalytic activity, by employing photochemical catalysis materials of TiO2 toumaline and methyl orange as target of degrading decolorizafion. The results show that tourmaline is helpful for TiO2 photo -catalysts to improve photo -catalytic activity, for which 1% tourmaline doping ratio is the best; the increase of catalyst will promote the degradation of methyl orange. Photo - catalytic degradation of methyl orange as the effect of the catalyst under conditions of 0.2 g methyl orange concentration of 40 mg· L^-1 is the best. |
