生物炭对有机无机污染物的修复作用与机理研究进展

Remediation of Organic and Inorganic pollutants by Biochar: A Review

生物炭作为高温热解下富碳、多孔的特殊结构和功能有机资源,在结构修复、吸附改良、水分持留、肥料缓释及土壤固碳减排等方面具有非常重要的作用。作为一种新型有机无机物的修复材料,生物炭由于其炭源材料、热解温度及速率各异而体现出系列吸附特征。综述了不同碳源材料置于各种缺氧热解制备条件下生成的各类生物炭对有机无机物料的吸附作用及其吸附解析机理,在此基础上,对生物炭吸附能力的科学表达形式及其应用前景进行了展望。

Biochar, as a carbon- enriched organic matter from pyrolysis with specific structure and function, played important roles in structural remediation, adsorption, increasing water holding capacity, improving slow release of fertilizer, enhancing carbon fixation and reducing gas emission etc. In this review, effects of biochar on organic and inorganic material remediation and related mechanisms were summarized. And then future research directions were proposed.
