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10 mg/L),反应60 min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 re-suits show that adding petroleum coke cannot significantly improve the degradation efficiency of p-CBA by ozone, but can promote mineralization of p-CBA by ozone. The removal of TOC by AC prepared by petro-leum coke after water pretreatment is better than that by AC prepared by petroleum coke after acid pre-treatment. When Ni/AC catalyst is applied for catalytic ozonation of p-CBA, and the initial p-CBA con-centration is 10 mg/L, the removal rates of p-CBA and TOC are 100% and 60% respectively after 60 min.
