摘 要:重金属难以降解且具有富集性,是一种极具危害的污染物。近年来,重金属污染事件不断增加,严重威胁着生态环境和人体健康。目前,治理水体中重金属的方法主要包括离子交换法、化学沉淀法、膜分离法和吸附法等。其中,吸附法因其操作简单、原料来源广泛、成本低、可回收等优点得到广泛应用。而炭基材料作为多孔材料,具有孔隙结构丰富,比表面积大等特点,被看作为理想的吸附剂并对其开展了大量研究。本文综述了近年来各种常见的炭基材料在处理水环境重金属污染方面的研究进展,在此基础上对吸附法处理重金属污染的应用前景进行了展望。Heavy metals are highly hazardous pollutants that are difficult to degrade and have a tendency to accumulate in the environment.In recent years,the number of heavy metal pollution incidents has been increasing,posing a serious threat to the ecological environment and human health.Currently,the methods for treating waterborne heavy metal pollution mainly include ion exchange,chemical precipitation,membrane separation,and adsorption.Among them,adsorption methods have been widely used due to their simplicity of operation,wide availability of raw materials,low cost,and recyclability.Carbon-based materials,as porous materials with high surface area,have been extensively studied and considered as ideal adsorbents.This article reviews the recent research progress on various common carbon-based materials in the treatment of heavy metal pollution in water environments and provides an outlook on the future application prospects of adsorption methods in the treatment of heavy metal pollution.
