| 摘 要： | 介绍了近年来有机酸与矿物之间相互作用的研究进展，重点探讨有机还可能与矿物间相互作用的环境意义、作用模式以及低分子量有机酸和高分子量腐殖酸在与矿物作用时各自的特点和彼此间的差异。有机酸-矿物界面作用控制着金属、有机污染物的迁移、转化与归宿以及生物可给性。有机酸-矿物界面作用存在多种模式，主要受有机酸和矿物的活性基团类型、含量分布以及有机酸分子量大小和疏水性等因素的影响。

| Abstract: | In this paper, the recent advance in the study of the interactions between minerals and organic acids (both of small molecules and of large molecules) is presented. The stress is placed on the environmental significance and the mechanisms of the interactions at the interface between organic acids and minerals. The characteristics associated with the interactions and the difference in reactivity between small molecule organic acid and humic acid are discussed too. The interactions can control the transport, transformation and eventual fate of metals and organic contaminants as well as nutrient availability for biota. The interactions involve coexisting multiform mechanisms. The mechanisms are mainly affected by such factors as surface functional groups of organic acids and minerals, their content distribution, and the molecule mass and hydrophobic property of organic acids. The objective of this study is to raise the understanding of the interactions between minerals and organic acids as well as their environmental significance. |
