| 摘 要： | 采用TiO2/UV光催化降解法处理对甲基苯磺酸的水溶液,探讨了二氧化钛的投加量、溶液的初始浓度、溶液的pH、紫外光照射时间和强度、常见无机离子等因素对对甲基苯磺酸的降解效率的影响.结果表明,在浓度为0.030 g·L-1对甲基苯磺酸溶液中,光催化剂TiO2最佳投加量为0.10 g·L-1,控制空气分压为5.2kPa,紫外光照射2h,溶液为中性时,对甲基苯磺酸废水降解率达到67.4%.二氧化钛的用量、溶液的pH是影响纳米TiO2光催化降解对甲基苯磺酸的主要因素.在此基础上还考察了无机阳离子和无机阴离子对反应的影响,并取得了满意的效果.

| Abstract: | Photocatalytic degradation of 4-Toluene sulfonic acid in aqueous solution by TiO2 under UVirradiation was studied. The effects of quantity of TiO2, concentration of 4-Toluene sulfonic acid,time and intensity of UVradiation, pHvalue of solution, and common inorganic ions was investigated. The results show that the optimal quantity of TiO2 was 0.10 g·L-1 in 0.030g·L-14-Toluene sulfonic acid solution under an air pressure of 5.2 kPa. Under those conditions, the degradation efficiency of 4-Toluene sulfonic acid was 67.4 % after 2 h UVirradiation at pH 7. The quantity of TiO2 and solution pHwere the main factors affecting the degradation of 4-Toluene sulfonic acid by nano-TiO2 The influences of some common inorganic ions were also studied, and the result was satisfying. |
