摘要
采用紫外激活过硫酸钠体系(UV/PS)降解水中的氯苯,考察了初始p H值、过硫酸盐投加量、氯苯初始浓度、氯离子浓度等对氯苯降解的影响。实验结果表明:氯苯初始浓度为20 mg/L,初始p H值为5,过硫酸盐投加量为200 mg/L条件下,氯苯的去除率达到了98.6%。氯离子对氯苯的去除有一定影响,当Cl-浓度大于15 mmol/L时,氯苯的降解效率明显下降。
UV-activated persulfate oxidation system was used to remove chlorobenzene in aqueous solution.The effects of initial pH value,initial concentration of chlorobenzene,dosage of sodium persulfate and chloride ion concentration were investigated.The experimental results showed that the removal rate of chlorobenzene reached 98.6%under the conditions of initial mass concentration of chlorobenzene 20 mg·L^(-1),initial pH of 5,persulfate dosage of 200 mg·L^(-1).Chloride ion had effect on the removal of chlorobenzene.When the concentration of chloride ion was more than 15 mmol·L^(-1),the degradation efficiency of chlorobenzene decreased obviously.
