摘 要: 锑是一种具有潜在毒性和致癌性的有色金属元素，随着锑及其化合物的广泛应用，大量含锑污染物进入水体中，给生态环境和人类健康带来风险。锑的毒性及其在水中的含量与形态结构密切相关，锑在复杂水体环境中的迁移转化规律是锑污染控制的理论基础。综述了近年来国内外对水中锑的形态及其氧化和还原、水解和配位、吸附和解吸、溶解和沉淀等迁移转化规律的研究进展，基于此对水体中锑的污染防治及未来研究重点作了展望。

Abstract:Antimony(Sb), as a kind of hazardous contamination, has potential toxicity and carcinogenicity. With the wide application of Sb-containing compounds, a large number of Sb-containing pollutants has been distributed throughout the environment as a result of mining and smelting, which brings risks to the ecological environment and human health. The toxicity and content of Sb in water are strongly associated with its species. The Sb speciation in water and its migration and transformation in complex environment are the theoretical basis of Sb contamination control. This paper reviewed the research progress of the speciation, oxidation and reduction, hydrolysis and coordination, adsorption and desorption, dissolution and precipitation of Sb in water. Based on above, Sb pollution control in water was prospected.
Key words: antimony; pollution characteristics; chemical speciation; migration and transformation
