| 摘 要： | 以TiO2为催化剂,对有机颜料艳红RGS母液进行了一系列光催化降解试验.考察了催化剂用量、溶液pH值、初始浓度、不同光源和照射时间对脱色率的影响.结果表明,溶液相对初始浓度为0.2、pH<8、催化剂用量为1g/L时,以紫外灯(254nm)为光源,反应120 min,脱色率可达93%以上.

| Abstract: | In this study,TiO2 was used to be degraded organic pigment wastewater of brilliant red RGS in UV-vis region.The effects of the dosage of catalyst,initial concentration of wastewater,pH value,all kinds of light sources and irradiation time were investigated.The results indicated that it had high photocatalytic activity in UV region(254 nm).When the dosage was 1g/L,pH<8,the relative initial concentration of wastewater was 0.2 and irradiation time was 120 min,the decolorization rate was above 93%. |
