摘　　要：采用铁屑对水中2,4-二氯苯酚进行了还原脱氯静态试验研究,考察了铁屑用量、反应时间、反应物浓度、反应物初始pH值及温度对脱氯率的影响,并对反应机理进行了初步的探讨。结果表明,铁屑微电池法还原脱氯经济、简便、有效,易于工业化。A static experimental research on reduction-dechlorination of 2,4-dechlorophenol was carried out with iron scraps .The influence of various factors, such as iron scrap dosage, reaction time, reaction substance concentration, initial pH and temperature, on de-chlorination rate was investigated and the reactive mechanism was enquired into primarily. The results showed that the iron scrap micro-cell process for reduction and dechlorination is economic,single and convenient,effective, and is easy to be industrialized.
