摘要
研究了在紫外光的照射下 ,由 Ti O2 催化分解染料酸性红 G和活性艳红 K- 2 G的行为 ,并且探讨了 Ti O2的添加量、染料结构、染料的初始浓度以及溶液 p H值等因素对上述 2种染料光催化分解的影响。实验结果表明 ,当Ti O2 的添加量为 3g· L- 1时 ,2种染料的催化分解率最大 ;在碱性条件下 (p H=8.5 )的分解效果好于酸性条件 (p H=5 .5 )
The photocatalytic degradations of acid red G and reactive brilliant red K-2G by TiO_2 suspension under the condition of the ultraviolet irradiation were studied. Spectrophotometer was used to determine the variations of each concentration during the degradation processes of the dyes. The influences of pH, initial concentration of dyes and TiO_2 dosage were investigated. The optimum conditions of the photocatalytic degradation of the dyes were obtained in the experiments.
