摘　　要：采用室内模拟研究,以P-25纳米TiO2作为光催化剂进行了苯酚水溶液的光催化降解性能探讨,初步考察了溶液的pH、P-25纳米TiO2用量对光催化降解苯酚过程的影响,以获得P-25纳米TiO2光降解含酚废水的较好反应条件。实验结果表明,当溶液pH=8时,降解水体中苯酚效果最佳,强酸和强碱条件均不利于苯酚的降解;在pH 8的反应体系中,当光催化剂用量为0.4g/L时,催化水体中苯酚降解的效果最好。Photocatalytic degradation of phenol solution by TiO2P-25 titanium dioxide was carried out.Two important factors,pH and quantity of TiO2P-25 were investigated preliminarily,which could make us get the better reaction conditions of TiO2P-25.The results showed that the high degradation efficiency could be reached when pH was 8,and when the quantities of photocatalyst TiO2P-25 was 0.4g/L,the effect was best.
