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。

Abstract

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 conditions: pH of 4~5,quantity of zerovalent iron of 5~6g, initial solution concentration of 350~500mg/L and ironcarbon ratios of 1.5~5.
