摘要
土壤中的重金属会对人类健康产生不利影响。生物炭因具有独特的物理和化学特性,在治理土壤污染方面受到广泛的关注。综述了土壤重金属污染现状、生物炭的性质与制备、生物炭对重金属的吸附机制及其修复效果,以及生物炭在土壤重金属污染修复中的应用现状,总结了当前生物炭修复技术面临的挑战。
Heavy metals in soil can pose adverse effects on human health.Biochar,with its unique physical and chemical properties,has attracted significant attention in soil pollution remediation,demonstrating great potential in the remediation of heavy metal contamination.This paper primarily reviews the current status of soil heavy metal pollution,the properties and preparation of biochar,the adsorption mechanisms and remediation effects of biochar for heavy metals,,and the application status of biochar in the remediation of heavy metal-contaminated soil.Finally,the challenges faced by current biochar remediation technologies are summarized.
