摘    要:天然胶体在土壤和地下水环境中广泛存在。由于胶体不仅具有粒径小、比表面积大、表面带有电荷等基本特点,而且具有独特的双电层结构和丰富的表面官能团,这些特点使得胶体成为地下环境中最为活跃的组分,并对土壤与地下水中污染物的迁移产生重要影响。近年来,土壤与地下水环境中的胶体及其对污染物的促进迁移作用受到越来越多研究者的关注。综述了地下环境中的胶体来源、可移动胶体的释放与沉积、胶体自身的特征与环境行为以及胶体对不同污染物的促进迁移作用,分析了各种环境因子对胶体-污染物共迁移的影响。在此基础上,对地下环境中胶体与污染物共迁移的过程与机理等尚需深入研究的关键科学问题提出了研究展望。

关 键 词:地下水  胶体  土壤污染  共迁移  吸附  环境因子

Abstract:Natural colloids in the soil and groundwater environments are ubiquitous.Since colloids possess not only small particle size, greater specific area and surface-charged, but also a unique double-layer structure and rich surface functional groups, which make them the most active components in subsurface environment and play an important role on contaminants transport in soil and groundwater.The colloids facilitated contaminant transport in soil and groundwater environment has drawn much attention in recent years.This paper reviews the sources, release/deposition, characteristics of colloids and their environmental behavior in subsurface environment, as well as the colloids facilitated transport of different contaminants, and analyzes various environmental factors on co-transport of contaminants with colloids.The key scientific questions, further prospective of processes and mechanism of co-transport of contaminants with colloids in subsurface environment are then proposed.
Keywords:groundwater  colloids  soil pollution  co-transport  adsorption  environmental factors
