摘要
对零价铁体系中邻氯苯酚的降解规律和影响因素进行了研究。采用间歇实验的方法，分别考察了pH值、铁粉添加量、初始浓度和铁碳比对邻氯苯酚去除率的影响。结果表明，邻氯苯酚在零价铁作用下，降解规律符合一级反应动力学模型；在本实验条件下，零价铁降解邻氯苯酚的最佳pH值为4～5，铁粉添加量为5～6g，溶液初始浓度为350～500mg／L，铁碳质量比为1．5～5。
The factors affecting the degradation of o-chlorophenol in zerovalent iron systems have been investigated. Laboratory batch experiments were run with varying pH values, quantities of zerovalent iron, initial solution concentration and iron-carbon ratios. The results show that the degradation of o-chlorophenol follows a first-order kinetics model. Degradation of o-chiorophenol was found to be maximized under the following condi- tions： pH of 4-5, quantity of zerovalent iron of 5 - 6 g, initial solution concentration of 350 - 500 mg/L and iron-carbon ratios of 1.5 - 5.
