摘　　要：重金属在自然界中通常以伴生形式与其他矿物共存,易在采选、冶炼及下游产业的生产和使用过程中释放并造成环境污染。重金属普遍存在难降解、易富集、高毒害的特征,因而其污染处置已成为世界难题。重金属捕集剂由于在去除重金属污染方面具有高效、广谱、环保、经济等优点,因而成为研究热点受到广泛关注。综合分析了重金属捕集剂的研究与应用进展,进一步揭示了重金属捕集剂的主要类别、作用机理和处理效果,指出了重金属捕集剂在应用过程中存在的关键问题及未来的研究方向,对重金属污染治理和新型捕集剂的研究开发具有较好的理论指导和技术支撑作用。In nature, heavy metals usually coexist with other minerals in the associated form and are released into the environment during the production, utilizing process of mining, smelting and downstream industries, which results in deterimental pollution. Heavy metals are generally difficult to be biodegraded, easy to enrich and high toxic. Therefore, it becomes a worldwide problem. Heavy metal capturing agents have advantages of high efficiency, wide spectrum, environmental-friendliness, economy, etc. in removing heavy metal pollutions, which make it become a research hotspot and attracting widespread attention. This review comprehensively analysed the research and application progress of heavy metal capturing agents, further analysed and revealed their primary categories, processing mechanisms and treatment effects, pointed out the key problems existing in the application and improvement direction in future. This review had a good theoretical guidance and technical support for the research and development of heavy metal pollution treatment technologies and novel heavy metal capturing agents.
