| Abstract: | In this paper, an ion- exchange HPLC method for the separation and determination of phosphate and phosphite in waste water of electrodes plating of nickel had been built up. The method used a Hamilton PRP-X100 anion column for separation, an aqueous of 5m mole p- hydroxybenzoic acid (pH 7.5) as mobile phase, a flow rate of 3ml/ min . and a conductivity detector for detection, and it had a resolution that was larger than 1.5 (phosphate/ phosphite), a lowest detection limit of 0.4 ppm for phosphite and 1.4 ppm for phosphate. The procedures of the pretreatment of sampl had been researched. |
