ABSTRACT OBJECTIVE To establish an ion chromatography method for the simultaneous determination of chloride, sulfate
and bicarbonate ions in Polyethylene glycol electrolyte powder (Ⅲ). METHODS The chromatographic column was a Dionex
Ionpac AS11-HC anion analysis column, with a Dionex IonPac AG11-HC guard column. The mobile phase was 10 mmol/L

potassium hydroxide at an isocratic elution flow rate of 1.2 mL/min. The detector was a conductivity detector, and the suppressor
was a Dionex AERS with a suppressor current of 30 mA. The column temperature was maintained at 30 °C, and the injection
volume was 10 μL. Chloride and sulfate contents were calculated by external standard method, while bicarbonate content was
determined by double logarithmic fitting standard curve method. RESULTS Under these chromatographic conditions, chloride,
sulfate and bicarbonate ions were effectively separated with linear ranges of 0.055 to 0.219 mg/mL (r=0.999 9), 0.155 to 0.618 mg/mL
(r=1.000 0), and 0.065 to 0.121 mg/mL (r=0.999 9), respectively. The recoveries were 98.06% to 101.34%, 97.37% to
101.25%, and 97.16% to 99.81%, respectively, with RSDs of 1.1%, 1.3% and 1.0% (n=9). The RSDs for the evaluation of
precision, accuracy, stability and ruggedness were all less than 2%. CONCLUSIONS The established ion chromatography is
simple, rapid, accurate, precise and durable, can simultaneously determine the contents of chloride, sulfate and bicarbonate ions in
Polyethylene glycol electrolyte powder (Ⅲ), which is suitable for its quality control.
