摘要:

采用浸渍法制备新型负载型催化剂CeAC, 并通过X射线荧光光谱(XFR)对其进行表征; 将其作为催化剂, 考察臭氧多相催化氧化工艺对水中微量污染物芘和荧蒽两种多环芳烃化合物(PAHs)的去除效果. 对比不同工艺及不同影响因素下的处理效果, 分析去除机理, 并对处理前后水样的生物毒性进行检测实验. 结果表明, 铈催化剂参与的臭氧多相催化氧化工艺对芘和荧蒽的去除效果较好, 处理条件温和, 处理后的水样毒性变小.

关键词: 臭氧, 多相催化氧化, 芘, 荧蒽, 新型负载型催化剂Ce-AC

Abstract:

A new catalyst CeAC was prepared by impregnating activated carbon (AC) into the solution of cerium nitrate. CeAC catalyst was characterized by XRF. During the CeAC  heterogeneous catalyzed ozonation, the different removal effcts of pyrene and fluoranthene in different treatment processes and a series of different conditions  were compared. The biotoxicity of the treated water was detected. The mechanism of the reaction was also discussed.

Key words: ozone, heterogeneous catalytic ozonation, pyrene, fluoranthene, new kind of catalyst CeAC
