Abstract The anions $H_{2}PO_{2}^{-},$ $H_{2}PO_{3}^{-}$ and $H_{2}PO_{4}^{-}$ along with $Cl^{-},$ $NO_{3}^{-}$ and $SO_{4}^{2-}$ have been simultaneously determined by single-column ion chromatography in an indirect ultraviolet detection mode. The analytical approach employs 4- amino-2-hydroxybenzoic acid as an eluent at 4mM in the pH range 5.5-6.5 and at a 2ml/min flow rate. Clean separations occur on a polymeric analytical column within 10min, and the anions can be quantified in the sub-ppm range.
