| 摘 要： | 本文以TiO_2为催化剂,采用中压汞灯为光源对偶氮染料溶液进行了光催化降解的研究。研究表明,该实验能够使直接R-F偶氮染料水溶液降解脱色,该反应为动力学一级反应。染料初始浓度在50mg·L~(-1),温度在20±1℃,经20min光照,其脱色率为97.0％以上;COD_(cr)去除率为60％左右。

| Abstract: | This article is about photocatalytic degradation of azo dye immediacy R-F solution. The result shows that the experiment can make dye immediacy R-F solution decolor, the reaction is kinetic first -scale reaction. Under the experiment conditions, the decolorization efficiency and removal efficiencies of CODCTcan reach 97% and 60% respectively by reaction 20 minutes at 20±1℃ |
