超声TiO2光催化协同降解对氨基偶氮苯废水

目的 为了处理废水，研究了含低浓度对氨基偶氮苯水溶液的降解反应。方法 采用超声辐射与TiO3光催化耦合的方式。结果 与单一的超声空化降解以及TiO2光催化降解相比较，在耦合作用下对氨基偶氮苯水溶液表现出了更高的降解效率。结论 实验证明对氨基偶氮苯水溶液的降解反应受到超声波输入功率以及O2浓度的影响，其中超声波功率越强，O2浓度越高，对氨基偶氮苯的降解速率越快。

Sonophotocatalytical synergistic degradation of benzidine wastewater by TiO2 catalysts

Aim Degradation reaction of selected model substrate bencidine aqueous is investigated.Methods Combination of sonolysis and TiO_2 photolysis.Results The decomposition rate of benzidine can be enhanced obviously in comparison alone with sonolysis and photocatalysis.Conculsion The degradation reaction of benzidine aqueous are severely influenced by ultrasonic power and concentration of O_2,thereinto,the better for the ultrasonic power and the more for the concentration of O_2,the more of the degradation efficiency for the benzidine aqueous.
