摘　　要：重金属污染已经成为当下环境修复领域的世界性问题之一,由于其具有毒理性、稳固性和持久性,已然成为威胁生态系统和生物健康亟待解决的重要问题。针对废水中铜、铅、镉、铬、镍和砷等重金属污染元素的吸附处理,将吸附材料按照来源和组成划分为天然矿物吸附材料、改性合成吸附材料(包括有机组成、硅基组成和碳基组成)以及微生物吸附材料,系统介绍了最新的研究成果和方法,并评估了原始及其功能化后吸附材料的优势和局限性,同时总结了吸附机理并对新型吸附处理技术和材料提出了展望。Heavy metal pollution has become one of the worldwide problems in the field of environmental remediation.Due to its toxicity,stability and persistence,it has become an important problem that threatens the ecosystem and biological health and needs to be solved urgently.Based on waste water in copper,lead,cadmium,chromium,nickel and the heavy metal pollution element such as arsenic adsorption process,could be divided into natural adsorption materials according to the source and composition of mineral adsorption materials,modified synthetic materials(including organic composition,composition of silicon and carbon composition)and microbial adsorption material.The latest research results and methods were systematically introduced,and the advantages and limitations of the original and functionalized adsorption materials were evaluated.The adsorption mechanism was summarized,and the new adsorption treatment technology and materials were prospected.
