摘要： 通过等体积浸渍法制备了CuO/γ-Al₂O₃催化剂，并对非均相微波协同类Fenton催化降解苯酚溶液进行了实验研究。实验结果表明，在溶液初始pH为6，H₂O₂投加量为4 mL/L，催化剂投加量为4 g/L，微波功率为500 W，反应时间为13 min的条件下，苯酚降解率可达98%，TOC去除率为62%。催化剂重复使用9次后，苯酚降解率为90.88%。通过比较不同氧化体系处理效果及添加·OH捕获剂证实，微波-催化剂-H₂O₂产生了明显的协同作用。

Abstract: CuO/γ-Al₂O₃ catalyst has been prepared by isopyknic impregnation method,and the experimental research on catalytic degradation of phenol solution by heterogeneous microwave-synergetic Fenton-like accomplished. The results show that under the following optimal conditions:initial pH of the solution is 6,H₂O₂ dosage 4 mL/L, catalyst dosage 4 g/L,microwave power 500 W,and reaction time 13 min,the phenol degradation rate can reach 98% and TOC removing rate is 62%. After the catalyst has been used 9 times repeatedly,the phenol degradation rate is 90.88%. It is verified that by comparing the treatment effects of different oxidation systems and adding ·OH trapping agent,the microwave-catalyst-H₂O₂ brings about obvious synergy.

Key words: microwave, Fenton-like, catalyst, phenol
