摘　　要：文章研究了高铁酸钾协同365 nm紫外光降解对氯苯酚,考察了高铁酸盐投加量、pH值和初始浓度对对氯苯酚去除率的影响并对比了单独高铁酸钾和复合体下的矿化率。实验结果表明:在高铁酸钾与对氯苯酚的摩尔比为4:1,对氯苯酚初始浓度为8 mg/L,pH为4时去除率为49%,比单独高铁酸盐处理降解率提高了11%。矿化率提高了6%。动力学结果表明降解过程为准一级动力学过程。This paper studies the degradation of p-chlorophenol by combining potassium ferrate with 365 nm UV（ultra violet） and the effect of additional dosage of potassium ferrate, PH and initial concentration on the removal rate of p-chlorophenol. And the mineralization ratio of sole potassium ferrate and composite are compared. It is found that the removal rate is 49% when the pH is 4, which is 11% higher than the sole potassium ferrate do and the mineralization ratio is increased by 6% under the conditions that mole ratio of potassium ferrate and p-chlorophenol is 4：1, the initial concentration of p-chlorophenol is 8mg L-1,.Kinetic results indicates that the degradation process of p-chlorophenol belongs to the process of pseudo first- order kinetics.
