摘要
[目的]研究磷钨酸/TiO2去除剂对甲醛的去除效果。[方法]通过制备纳米TiO2负载磷钨酸甲醛去除剂,研究其最佳负载比,并研究其甲醛去除效率、并与纳米银去除剂、甲醛吸收液进行比较。[结果]可见光照射下,磷钨酸/TiO2去除剂对甲醛的去除率高达69.00%,而且与纳米银催化剂相比,成本较低,更具市场可行性。[结论]该研究为室内空气污染的去除提供了更为环保和节能的途径。
[ Objective ] The study aims to discuss the removal effect of phosphotungstic acid/TiO2 on formaldehyde. L Method ] A new remover phosphotungstic acid/TiO2 was prepared firstly, and the optimal ratio of phosphotungstic acid to TiO2 was determined. Moreover, we compared the removal effects of phosphotungstic acid/TiO2, nano-s｜iver and formaldehyde absorption solution on formaldehyde. [ Result] Under visible light, the removal rate of phosphotungstic acid/TiO2 on formaldehyde reached 69.00%, and its cost is lower compared with catalyst nano-sliv- er, more feasible in the market. [ Conclusion ] The research could provide a greener and more energy-saving way to remove indoor air pollutants.
