摘要
在分析土壤中砷的来源及存在形态的基础上,简要探讨了不同形态砷之间相互转化的过程.对土壤砷形态的提取和检测方法进行了较系统的比较,认为高效液相色谱-氢化物发生-原子荧光光谱(HPLC-HG-AFS)联用技术具有灵敏度高、检测限低、选择性强、运行成本低、不同形态砷之间相互转化较少的优点,可以作为砷形态检测的首选方法.结合相关研究结果,对土壤中砷形态转化及相关研究的发展方向进行了讨论.
Based on the analysis of the sources and existing forms of soil arsenic, this paper ap proached the inter-transformation of different arsenic forms in soil. In the meanwhile, the extraction and determination methods of different soil arsenic forms were also compared. It was considered that HPLC-HG-AFS had the advantages of high sensitivity, low detection limit, better selectivity, low operation cost, and less inter-transformation of different arsenic forms, being able to be used as the prior method for the detection of different arsenic the form transformation of arsenic in soil and the forms. Combining with previous research results, promising research aspects were also discussed.
