title: [Form transformation of arsenic in soil and corresponding analyzing methods].
abstract: Based on the analysis of the sources and existing forms of soil arsenic, this paper approached the inter-transformationr 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 forms. Combining with previous research results, the form transformation of arsenic in soil and the promising research aspects were also discussed.
