摘　　要：以过硫酸钾为氧化剂去除水和土壤中的苯胺,考察了反应温度、氧化剂浓度、初始p H等因素对氧化效果的影响。结果表明,当反应温度为40℃、过硫酸钾浓度为103.0 mmolL、初始p H为5~11时,水中苯胺的降解效果最佳,降解率可达94.1%。当反应温度为40℃、过硫酸钾浓度为1.2 molL时,土壤中苯胺的降解率达到98.9%。表明过硫酸钾能够有效去除水和土壤中的苯胺,可作为苯胺污染物应急处置的一种可能的方法。The degradation of aniline by potassium persulfate was investigated in aqueous solutions and soils. The influence factors such as the temperature,oxidant concentration and initial p H were explored. The results indicated that in aqueous solutions,under the conditions of reaction temperature of 40 ℃,potassium persulfate concentration of 103. 0 mmolL and p H range of 5-11,the optimal aniline degradation effect could be obtained with aniline degradation efficiency of 94. 1%. The results showed that the removal of aniline could reach 98. 9% at the condition of 40 ℃ with potassium persulfate concentration of 1. 2 molL. Therefore potassium persulfate can be used to effectively degrade the aniline in water and soils,which provides a possible approach for the emergency management of aniline contaminant.
