摘　　要：化学钝化修复技术作为修复重金属污染土壤的重要方法之一,成本低、操作简单、修复效率高,具有良好的应用前景。钝化剂类型多样,分布广泛,可分为无机类钝化剂、有机类钝化剂、微生物类钝化剂、复合型钝化剂及新型材料钝化剂,不同类型的钝化剂对重金属污染土壤的钝化修复效果各不相同。主要从各类型钝化剂的自身特性、作用机理、修复效果概述了钝化剂的研究进展和前景,分析了存在的问题,并从钝化剂的合理施用、风险评估、长期有效性、完善分类系统、修复方法集成等方面提出展望,以期为钝化修复重金属污染土壤提供参考。As one of the important methods for the remediation of heavy metals contaminated soil chemical remediation technology,the technology of low cost, simple operation, and high repair efficiency, and has good application prospect, and has become a research hotspot in research and development, which is highly concerned by passivator. The types of the passivation agents are diverse and widely distributed, which can be divided into inorganic passivation agent, organic passivation agent, microbial passivation agent and composite passivation agent. Different types of passivation agents have different effects on the remediation of heavy metal contaminated soils. This article mainly from the various types of passivation characteristics, action mechanism and repair effect summarizes the research development and prospect of passivator, analyzes the existing problems, and from the rational application of passivant and risk assessment, long-term effectiveness, improve the classification system, and other aspects of repair method integration technology is put forward to provide a theoretical basis for the remediation of heavy metal contaminated soil area.
