土壤中锑源解析方法探讨

Discussion on Analytical Methods for Antimony Sources in Urban Soil

综述了近几年国内外文献对城市土壤中锑的主要来源以及锑在土壤中迁移转化过程发生的形态变化,并对目前常用的重金属来源分析方法包括稳定同位素示踪法和化学形态分析法等方法进行分析比较。锑已被广泛应用于阻燃剂、催化剂以及合金等的生产,含锑产品在生产和使用过程中释放,汇入土壤。由于锑的潜在毒性和风险,锑越来越被人关注,对土壤中锑来源的分析的需求也越来越迫切,但目前对锑源解析的研究还比较少。综述了近几年国内外文献中对土壤中锑的主要来源以及锑在土壤中迁移转化过程发生的形态变化的研究,并对目前常用的重金属来源分析方法包括稳定同位素示踪法和化学形态分析法进行分析比较,为土壤中锑来源解析提供一定的参考。

Based on the domestic and foreign literatures in recent years,the article reviewed the main sources of antimony in urban soil and the morphological changes that occur during the migration and transformation of antimony in the soil,analyzed and compared the commonly used heavy metal source analysis methods including stable isotope tracer method and chemical speciation analysis method.Antimony has been widely used in the production of flame retardants,catalysts,alloys,etc.Products containing antimony are released in the process of production and use,and will be absorbed into the soil.Due to the potential toxicity and risks of antimony,antimony is getting more and more attention,and the demand for the analysis of the source of antimony in soil is becoming more and more urgent.However,there is little research on the analysis of antimony sources.This article reviewed the studies on the main sources of antimony in soil and the morphological changes that occur during the migration and transformation of antimony in soil,and analyzed and compared the commonly used heavy metal source analysis methods including stable isotope tracer method and chemical speciation analysis method.It provides some reference for the source analysis of antimony in soil.
