氯代有机物广泛应用于工业、农业和人类的日常生活中,这类有机物通过各种途径进入环境水体中.因为许多氯代有机物有毒,且在自然界中难于降解,这类物质在环境中的暴露对人类和生态环境具有极大的危害性,一直成为各国俦控制的污染物.钯化铁与氯代有机物进行的反应是在急化铁表面进行的,钯化铁中的急主要以零价钯的状态,分散在铁表面,对脱氯反应起催化加速的作用.脱氯反应可能的途径是直接电子转移,即铁为还原铁,水提供氢源直接参与的反应.三种氯酚与钯化铁反应生成产物为苯酚和氯离子.1,1,2,2-四氯乙烷,1,1,2-三氯乙烷和1,2-二氯乙烷与钯化铁反应的历程不同,生成的产物不同.但是它们都是在逐步脱氯,生成无毒或低毒的产物.钯化铁与氯苯酚及氯苯的脱氯反应,在以反应物浓度为标准的前提下是准一级反应.建立了氯代有机物的分子结构与脱氯反应速率的QSPR模型.
