摘要 研究了Fe(Ⅱ)/K2S2O8对水体中As(Ⅲ)的氧化作用,以及pH值、Fe(Ⅱ)初始浓度等因素对氧化As(Ⅲ)的影响,并且采用分子探针法的竞争性实验鉴定了体系中产生的活性中间体,探讨了K2S2O8在Fe(Ⅱ)存在的条件下对As(Ⅲ)的氧化机理。 Oxidation of As(Ⅲ) in water by iron(Ⅱ)-catalyzed potassium persulfate as well as the influence of various pH and initial concentration of Fe(Ⅱ) was investigated. The potential radicals and possible oxidation mechanism were also studied.
