摘　　要：胶体广泛存在于土壤中,因此,被认为是天然胶体的储存库。胶体颗粒粒径小,且具有巨大的表面能和表面电荷,使得胶体能吸附大量离子和有机污染物并稳定悬浮在分散剂中。有机污染物进入土壤多孔介质后,会在土壤、土壤溶液、土壤胶体这三项体系中迁移,而胶体是有机污染物迁移的关键载体。有机污染物对环境危害严重,所以对有机污染物迁移过程的研究逐步被研究者重视。本文综述了土壤胶体的三种类型、土壤胶体的释放条件及迁移的影响因素;探讨了有机污染物在土壤胶体中的吸附行为及土壤胶体对有机污染物迁移的作用研究。以期有利于人们更好地了解土壤胶体和有机污染物在土壤中的共迁移行为,为修复有机污染物污染土壤提供理论帮助。Colloids are widely present in soil and are therefore considered as storage reservoirs for natural colloids.Colloid particles are small in size,and have huge surface energy and surface charge,which enable the colloid to absorb a large number of ions and organic pollutants and stably suspend in the dispersant.When organic pollutants enter the soil porous medium,they will migrate in the three systems of soil,soil solution and soil colloid,and colloid is the key carrier of organic pollutants migration.Organic pollutants pose a serious threat to the environment,so research on the migration process of organic pollutants is gradually being paid attention to by researchers.This article summarizes three types of soil colloids,the release conditions of soil colloids,and the influencing factors of their migration.Explored the adsorption behavior of organic pollutants on soil colloids and the role of soil colloids in the migration of organic pollutants.In order to help people better understand the co migration behavior of soil colloids and organic pollutants in soil,and provide theoretical assistance for the remediation of organic pollutants contaminated soil.
