摘要: 以二水合钨酸钠和五水合硝酸铋为原料,水热法合成花球状片层钨酸铋,利用XRD、SEM、红外、拉曼对其表面形貌和微观结构进行了表征,并通过催化降解模型污染物甲基橙、土霉素以及盐酸二甲双胍来探究钨酸铋的光催化效果,进而将其广泛应用于医药废水的处理中。结果表明:水热法制备的花球状片层钨酸铋在可见光照射下具有较好的光催化效果,光照2.5 h后基本可以完全降解模型化合物。

Abstract: Flower spherelike bismuth tungstate was synthesized by hydrothermal method using sodium tungstate dihydrate and bismuth nitrate pentahydrate as raw materials. The surface morphology and microstructure were characterized by XRD, SEM, IR and Raman. The photocatalytic effect of bismuth tungstate was investigated by degrading model pollutants of methyl orange, oxytetracycline and metformin hydrochloride, and then it is widely used in the treatment of pharmaceutical wastewater. The results show that bismuth tungstate with spherical morphology prepared by hydrothermal method possessed good photocatalytic effect, and the model compounds can be completely degraded after 2.5 h.
Key words: bismuth tungstate; photocatalysis; methyl orange; oxytetracycline; metformin hydrochloride
