摘要
制备了磷钨酸四甲基铵,在光化学反应仪中,以紫外灯为光源,以磷钨酸四甲基铵为光催化剂,研究了其对模拟甲基橙染料废水的光催化脱色降解的影响.讨论了影响催化降解效果的重要因素:溶液初始酸度,催化剂投加量等.最后,在300W的紫外灯光照下,讨论了磷钨酸四甲基铵光催化剂的重复使用性.
Phosphotungstate was synthesizied and its photocatalytic degradation of methyl orange was studied by using ultraviolet lamp in photochemical reaction instrument. The several important factors of photocatalytic degradation, which included initial pH value of solution, catalyst quantity were also discussed. Finally, the retrievability of catalyst was investigated.
