  • 摘要: 比较研究了Fe2+、Co2+和Ag+活化Na2S2O8及KHSO5对土壤中芘的氧化降解效果，并对上述反应过程进行动力学研究及芘降解产物成分分析。在土水质量比为1：5，氧化剂和过渡金属离子添加摩尔比为10：1，30℃恒温水浴磁力搅拌及反应时间5~120 min条件下开展了系列实验。结果表明，3种离子中Fe2+活化Na2S2O8氧化降解芘的去除效果最优，反应120 min后芘去除率为93.4%；Co2+是活化KHSO5的最佳过渡金属离子，反应5 min后芘去除率达94.5%，在反应120 min后芘去除率增高至97.0%。此外，降解动力学拟合结果表明Fe2+、Co2+和Ag+活化Na2S2O8和KHSO5降解芘的过程符合准一级反应动力学，且土壤中绝大部分芘可被活化过硫酸盐体系氧化降解。
    Abstract: The degradation efficiency of pyrene in soil by Fe2+-,Co2+-,and Ag+-activated Na2S2O8 and KHSO5 was investigated comparatively,and the kinetics of the reaction process and by-products of pyrene were analyzed.The experiments were carried out with a soil-to-water weight ratio of 1:5,oxidant-to-transition-metal-ion molar ratio of 10:1,constant water bath temperature of 30℃ with magnetic stirring,and reaction time of 5 to 120 min.The results showed that Na2S2O8 activated by Fe2+ performed better in the removal of pyrene than the other two types of metal ions,and the obtained maximum removal yield of pyrene was 93.4% in the case of a reaction time of 120 min.In contrast,Co2+ was revealed to be the best transition metal ion for activating KHSO5 among the three types of metal ions,displaying a pyrene removal yield of 94.5% with a reaction time of 5 min,which increased to 97.0% at 120 min.Furthermore,the fitting results of degradation kinetics demonstrated that the pyrene degradation process by Fe2+-,Co2+-,and Ag+-activated Na2S2O8 and KHSO5 follows pseudo-first-order reaction kinetics,and the pyrene in soil was almost completely degraded by the activated persulfate system.
