| 摘 要： | 在总结大量文献的基础上,主要就腐殖质修复TNT污染土壤的机理进行了探讨。腐殖质具有较大比表面积,含有大量的羧基、酚羟基、羰基、醇羟基等官能团,能通过共价吸附、微孔吸附、疏水性吸附、静电吸附等与土壤中TNT及其转化产物相互作用,进而影响土壤中TNT及其转化产物的迁移和生态毒性。

| Abstract: | Based on the literature review, the paper discusses the mechanism of restoring the TNT-polluted soil by humus. The humus, with a large specific surface area, contains a great number of the functional groups such as car- boxyl, hydroxyl, carbonyl and alcohols. Through covalent bonds, microporous adsorption, hydrophobic adsorption, e- lectrostatic adsorption and hydrogen bonds, it interacts with TNT and its metabolites in soil, and then influences their ecological migration and toxicity. |
