纳米TiO_2光催化降解酸性红B的实验研究

Photocatalytic Degradation of Acid Red B by Nanometer TiO_2

采用偶联剂法在聚丙烯多面球表面负载化纳米TiO2,在高压汞灯照射下,以酸性红B染料为研究对象,采用光催化氧化法进行降解处理;研究了溶液初始浓度、H2O2和Fe3+投加量、pH以及光照强度等因素对酸性红B染料降解效果的影响。

Using immobilized nanometer TiO2 photocatatlyst,the photocatalytic degradation of acid red B under high pressure mercury lamp was studied.And factors of the interference of the degradation were also studied,including initial concentration of liquor,pH value,amount of H2O2 and Fe3+,irradiation intensity.
