          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.
