Abstract: Arsenic and antimony are typical anionic pollutants, and with the development of arsenic-antimony mineral resources, as well as the abuse of arsenic and antimony-containing pesticides and additives, arsenic and antimony pollution incidents in the environment often occur. The development of speciation analysis techniques for arsenic and antimony in environmental media is of great significance for the environmental regulation and pollution prevention of arsenic and antimony pollution. In this paper, the developed speciation analysis techniques for arsenic and antimony were reviewed, with particular attention to the development of current on-site speciation analysis techniques,
