摘要/Abstract

摘要： 以粉末活性炭(PAC)和颗粒活性炭(GAC)为载体，采用浸渍焙烧法制备了负载铜氧化物的活性炭催化剂，考察了其表面结构、元素组成及BET参数；以腐殖酸模拟废水为对象，研究了微波?载铜活性炭催化氧化降解腐殖酸的效果和影响因素，探讨了微波?催化氧化协同H2O2降解腐殖酸的机理. 结果表明，载铜活性炭比未负载铜的活性炭对腐殖酸的降解率更高，且Cu/PAC的催化效果远优于Cu/GAC，两种催化剂最佳的微波?催化氧化条件分别为Cu/PAC投加量1 g/L, H2O2投加量0.9 mL/L, pH=3，微波功率400 W，微波时间4 min和Cu/GAC投加量8 g/L, H2O2投加量1.5 mL/L, pH=6，微波功率400 W，微波时间4 min，该条件下腐殖酸的去除率分别为93.91%和91.59%. 微波、H2O2和催化剂协同作用对腐殖酸高效降解有决定性作用.
