| 摘 要： | 对水溶性染料曙红Y使用Fenton试剂结合光催化氧化降解褪色的过程进行了研究,对该反应的4种主要影响因素加以分析:染料浓度、Fenton试剂用量、光源、初始pH值。经过系列的研究分析得出了曙红Y降解的最佳降解条件,并对Fenton试剂光催化氧化反应机理进行了初步探讨。实验结果表明:太阳光照射能有效地促进曙红Y的降解褪色(脱色率大于95%),明显缩短褪色时间,节约氧化剂的用量。当Fe2+浓度在3.50×10-5~7.19×10-5mol/L之间以及H2O2的摩尔量为染料摩尔量的50~100倍时,太阳光光照能有效地促进0.10 g/L以下浓度的曙红Y的降解。

| Abstract: | In this paper,the photocatalysis degradation and decolorization of water soluble dye-Eosin Y under natural sun light and450W high pressure Hg-lamp irritation in the presence of photo-catalyst Fenton's reagent were studied.7factors were researched,namely:concentration of Eosin Y,dosage and ratio of Fenton's reagent,light source,original pH value of the solution and the addition of other chemicals.Through experiments the optimum condition for the decolorization of Eosin Y was decided.Experiments showthat sun light can promote this reaction apparently(percentage of decolorization is more than95%).The reaction time can be shortened and the dosage of Fenton's reagent was saved. |
