摘要:
研发功能性明显、安全和经济实用的环境材料是修复土壤重金属污染研究领域的一个重要方向。胡敏素是土壤有机质的重要组分,具有分子量大和不溶于酸碱溶液等特征,对土壤重金属的转化、迁移等方面起到关键性作用。对胡敏素来源、性质和修复土壤重金属污染的机制进行总结分析。提出胡敏素对土壤重金属污染的修复机理主要包括离子交换、静电吸附、物理吸附、络合反应和化学沉淀;结合胡敏素资源利用面临的问题,提出胡敏素改性是其重要的发展方向。通过实验证明,通过物理和化学方法改性后,胡敏素对重金属元素吸附钝化效果更突出。加强改性胡敏素在农田土壤重金属钝化效应和土壤改良等方面的规模试验,是其未来真正应用于重金属土壤污染修复需要开展的重要工作。
Abstract:
The research and development of functional, safe and economical environmental materials are an important research direction for soil remediation of heavy metal pollution. As an important component of soil organic matter, humin (HM) possesses the properties of large molecular weight and insolubility, and plays an important role in the transformation and migration of heavy metals in soil. This paper summarizes and analyzes the sources, properties and remediation mechanism of humin. The remediation mechanism of soil heavy metal pollution by humin mainly includes ion exchange, electrostatic adsorption, physical adsorption, complexation and chemical precipitation. Combining with the problems in the resources utilization of humin resources, we put forward the idea that the modification of humin is a major research direction. The results showed that the adsorption and passivation effect of humin is more prominent after physical and chemical modification. Strengthening the farmland soil experiments of humin remediation for heavy metal contamination is the inevitable course to the humin application in heavy metal contaminated soil remediation.
