摘要

溶解性有机质(DOM)是土壤溶液中的一个重要的组成部分,在土壤化学和生物过程中起着十分重要的作用。虽然DOM在天然有机质中所占的比例并不高,但它将土壤中的矿物质、有机质联系在一起,并能调控环境污染物的迁移转化与归宿,因此国内外学者都很重视溶解性有机质对土壤环境中污染物环境行为影响的研究。综述了DOM的分类和分离技术,DOM的结构及其表征方法,DOM的表面反应性以及对有机污染物、重金属在土壤中吸附、迁移的影响等,并提出了有待于进一步研究的一些问题。

Abstract：

Dissolved organic matter (DOM) is an important component in soil solution,it have vital function on soil chemical and biological process. Although DOM is just a little portion in the natural organic material,it connects mineral with organic material and controls the transference,transform and end-result of environmental pollutants. As a result,scholars round the world pay a lot of attention to the influence of organic material on soil pollutant's environmental action. This paper gives a review about the classify and separate technology of dissolved organic matter (DOM),with the information on the structure and the taken method of DOM,the surface reactivity of DOM and it's effect on the adsorption and transference of organic contamination and heavy metal in the soil. And some aspects for further research are also proposed.

Key words： Soil dissolved organic matter Classify Characterization method Surface reactivity
