| Abstract | A liquid-liquid extraction procedure for the elimination of high levels of sulfate is described. The proposed method allows the ion-chromatographic determination of ppb concentrations of phosphate in the presence of a 20 000-fold excess of sulfate. The liquid anion exchange resin Amberlite LA-2 was selected to retain sulfate from the sample solution acidified by acetic acid as well as cation-exchange cartridges in the H-form. The detection limit for phosphate was 0.03 mg/L. |
