| 在悬浮体系下考察了染料亚甲基蓝降解的影响因素。试验结果表明，染料的初始量和催化剂的加入量存在一个最佳值，过大的染料浓度和过多的催化剂量会降低对光的吸收从而降低了降解速率、酸度主要是影响了溶液中界面电荷性质、而则主要影响了羟基自由基的生产。在本试验条件下200mL的溶液中以加入60mg催化剂和10mg/L染料有最佳的降解效果,而适宜曝气量为0.5L/min时降解性能最佳，溶液在碱性条件下较为合适。溶液中亚甲基蓝的光催化降解动力学研究表明染料在高浓度下的降解呈一级动力学特征。 |

Test results show that the initial amount of dye and the addition of a catalyst exist a best value, higher concentration of dye and too much catalyst will reduce the amount of light absorption and thus reduce the rate of degradation, the acidity, and affect the nature of interface charge in the solution, and mainly affected the production of hydroxyl radicals. In the condition of this test, 200mL solution mixed in 60mg catalyst and 10mg / L dyes have the best effect of degradation, and appropriatelly 0.5L/min of aeration have the best performance degradation, and the solution in condition of alkaline is more appropriate. The study of photocatalytic degradation kinetics of Methylene Blue in solution showed that the degradation of dye in the high degradation is first order kinetics.
