| 摘 要： | 制备了磷钨杂多酸季铵盐-磷钨酸四甲基铵并对其进行了初步表征。在光催化反应仪中，以紫外灯为光源，以磷钨酸四甲基铵为光催化剂，探讨了光催化降解苯酚的最佳条件。实验结果表明，对于10mg／L的苯酚溶液。催化剂投加量为1．5g／L，在300W高压汞灯照射下，光催化降解8h，去除率可达89．9％，TOC去除率达85．1％。

| Abstract: | Phosphotungstate was prepared and characterized. Its photocatalytic degradation of phenol was studied by using ultraviolet lamp in photochemical reaction instrument. The optimal conditions of experiment were discussed. The experi- ment results showed the maximum photocatalytic degradation was 89.9% in 10 mg/L aqueous phenol, when the quality of catalyst was 1.5g/L and the time of photocatalytic degradation was 8 hours. |
