This paper set up a method for the determination of fluorine content in white granulated sugar by Ion Chromatography. The separation of the anions was achieved on an IonPac AS18 column with KOH as isocratic elution, suppressed conductivity detection. The detection limit is 0.02 mg/L, the standard addition recoveries was 99.21%~101.1%, the relative standard deviation (n=6) was 0.82%~1.23%. It turned out that the method is simple, rapid and accurate.
