| 摘 要： | 本实验研究了Keggin型杂多化合物Na3PW12O40／SiO2（二氧化硅负载的磷钨杂多酸钠）在紫外光的照射下催化降解有机染料甲基紫的效能。实验结果表明，催化剂用量不同，溶液的初始浓度，酸度不同则降解有机染料的效率不同。催化剂加入量的最佳值为0．09g／L；溶液的初始浓度为2mg／L时，降解的效果最佳；降解最适宜的初始酸度为pH=1。Keggin型杂多化合物Na3PW12O40／SiO2光催化降解甲基紫为一级动力学反应。

| Abstract: | Study on the efficiency of the Na3PW12O40/SiO2 in the photecatalytic degradation was carried out under different conditions. Methyl violet was used as the aims of degradation and a low pressure mercury lamp was taken as light source （25W）. The results show the optimal reaction condions are that the amount of the catalyst is 0.09g/L, the initial concentration of methyl violet solution is 2mg/L and the initial acidity is pH=. The reaction of photocatalytic degradation of methyl violet with Na3PW12O40/SiO2 follows the characteristic first--order reaction kinetics. |
