Abstract The separation of arylarsonic acids by HPLC on a reverse‐phase C 18 column is described. Solutions containing these arsenicals and others such as arsenobetaine are photo‐oxidized to arsenate by ultraviolet (UV) radiation (1200 W, 1 h exposure). This allows the analysis of the solution for arsenic by hydride generation techniques. The method, UV HGAA, is developed and applied to the determination of arsenic in the methanol extracts of the Manila clam (Verupis japonica) and the Horse clam (Schizothoerus nutalli).
