| 摘 要： | 制备了Dawson结构磷钨酸(H6P2W18O62.13H2O),通过UV-Vis及电化学方法分别对其结构和电化学性能进行了表征.以甲基橙溶液(MO)为模拟工业染料废水,研究Dawson结构磷钨酸在紫外光照射下催化剂的光催化性能.研究结果表明,在pH值2时,催化剂表现出较强的氧化还原能力;在优化条件下,即催化剂用量为1.5 g/L、甲基橙初始浓度为10 mg/L、紫外光照时间为120 min时,甲基橙降解率为93.83%.

| Abstract: | Dawson structure phosphotungstic acid was prepared and characted by means of UV-Vis and electrochemical methods.The degradation of methyl orange under the irradiation of ultraviolet light was carried out as a probe reaction to study the photo catalytic ability of the catalyst.The results showed that the catalyst exhibited an excellent oxidation-reduction ability when pH<2.Under the optimal condition,i.e.catalyst dosage 1.5 g/L,the initial concentration of methyl orange 10 mg/L,illumination time 120 min and pH<2,the degradation rate of methyl orange was more than 93.83%. |
