摘要/Abstract

摘要： 生物炭是在一定的温度、限氧（或隔氧）条件下通过热解生物质得到的产物, 通过介绍生物炭的概念、制备方法、理化性质等方面来提出生物炭治理土壤重金属污染的方法。利用生物炭或将生物炭与其他材料结合, 可以作为治理重金属污染的一条途径, 如利用生物炭的吸附作用来修复污染的土壤, 可以降低重金属离子的生物有效性, 对降低植物体内重金属含量也有一定的效果。但是当前的研究和修复手段仍然存在不足, 期望寻找到环保、科学、合理的材料和技术来修复土壤中的重金属污染。

Abstract: Biochar is a product obtained by pyrolysis of biomass under certain temperature and oxygen-limited（or oxygen-blocking） conditions. The method of biochar treatment of heavy metal pollution in soil is proposed by introducing the concept, preparation method and physicochemical properties of biochar. The use of biochar or the combination of biochar with other materials can be used as a way to control heavy metal pollution. The use of biochar adsorption to repair contaminated soil can reduce the bioavailability of heavy metal ions and reduce the heavy metal content in plants. However, current research and repair methods still have shortcomings, and it is expected to find environmentally friendly, scientific and reasonable materials and techniques to repair heavy metal pollution in the soil.

Key words: biochar, soil, heavy metal pollution, adsorption
