The Character of Serial Filter Solution’s Light Absorption and Application to Photocatalytic Experiment

研究了系列滤光液的光吸收特性,得出了其紫外-可见光吸收谱图,并利用其中的CuSO4溶液为滤光液,以苯酚为模拟污染物,对比了3种TiO2催化剂的光催化活性.结果表明,采用合适的滤光液,可降低模拟污染物的直接光降解作用,有效区别不同活性催化剂的催化活性,为光催化实验者提供了可资利用的系列滤光液谱图.

The character of light absorption＇s serial filter solution is studied, and the UV-light absorption spectrogram is obtained. When phenol was utilized as the stimulant contaminant, the photocatalytic activity of three TiO2 catalysts was compared used CuSO4 solution and distill water as filter solution, respectively. The result shows that when suitable filter solution was applied, the photo degradation of the stimulant contaminant was decreased and the photocatalytic activity of different photo catalysis was distincted effectively. The research provides light absorption spectrogram of serial filter solution for the photo-catalytic experimenter.
