摘　　要：利用水热合成法制备了Keggin结构的Fe-Mo-Zr杂多酸盐光催化剂,并利用红外光谱（IR）对催化剂进行了表征。实验以酸性大红（GR）为模拟污染物,考察了在紫外灯照射下,Fe-Mo-Zr杂多酸盐的投加量、污染物的浓度和pH值以及外加H2O2对光催化降解效果的影响。实验结果表明,当催化剂的投加量为0.6 g/L,pH为5-7,初始浓度为10 mg/L的GR染料溶液,光照160 min,脱色率可达87.98%。外加H2O2可以提高光催化反应效率。The photocatalyst of the heteropoly salt containing Fe-Mo-Zr was prepared with the hydrothermal synthesizes reactions and characterized by fourier transform infrared spectroscopy （FT-IR）. The influences of the amount of the photocatalyst, initial concentration of acidic great red （GR） , pH value of solution and H2O2 added were studied by degradation rate of GR under UV light irradiation. The results of the experiments show that the concentration of GR dye solution is 10 mg/L,and catalyst amount of Fe-Mo-Zr is 0.6 g/L ,and the pH is 5 - 7 with UV irradiation 160 min, the degradation rate of GR is up to 87.98%. In the system, H2O2 added can enhance the degradation rate of the GR solution.
