摘　　要：考察了石油焦、石油焦制备的活性炭(AC)及其负载Ni所制备的Ni/AC催化臭氧氧化对氯苯甲酸(p-CBA)的效果。结果表明,石油焦的加入对臭氧氧化降解p-CBA的效果没有明显改善,但有利于臭氧对p-CBA的矿化;采用水洗预处理石油焦制备的活性炭对TOC的去除效果比采用酸洗预处理方法的要好;采用石油焦制备活性炭后负载Ni所得的Ni/AC催化剂催化臭氧氧化p-CBA(初始浓度为10mg/L),反应60min后,对p-CBA的去除率达100%,对TOC的去除率达60%。The catalytic ozonation efficiencies of p-chlorobenzoic acid （p-CBA） by petroleum coke, activated carbon （AC） prepared by petroleum coke and Ni/AC catalyst were investigated. The resuits show that adding petroleum coke cannot significantly improve the degradation efficiency ofp-CBA by ozone, but can promote mineralization ofp-CBA by ozone. The removal of TOC by AC prepared by petroleum coke after water pretreatment is better than that by AC prepared by petroleum coke after acid pretreatment： When Ni/AC catalyst is applied for catalytic ozonation of p-CBA, and the initial p-CBA concentration is 10 mg/L, the removal rates of p-CBA and TOC are 100% and 60% respectively after 60 mill.
