摘　　要：以钴钨酸钾为催化剂,在紫外灯照射下,对亚甲基蓝溶液进行了光催化降解的实验研究.考察了钴钨酸钾的用量、亚甲基蓝初始浓度及溶液pH值等因素对降解效果的影响.结果表明:用钴钨酸钾催化剂降解亚甲基蓝的效果较好,降解率可以达到96%以上,重复性良好.In this paper, the degradation of the methylene blue （MB） was investigated by employing potassium dodecatungstocobaltate as catalyst under UV irradiation. The effects of various factors, such as catalyst dosage,the initial concentration of the MB and the pH value of the solution on degradation efficiency were systematically studied. The results showed that potassium dodecatungstocobaltate is a well-performed photocatalyst for degradating MB with the degradation rate over 96% and good reproducitivity.
