AB  - A single pump cycling-column-switching technique has been developed for the 
      iodate analysis in edible salt. Homemade high exchange capacity columns were 
      adopted for the separation of iodate and chloride. Iodate could be retained and 
      concentrated in a homemade concentrator column after eluents passing through the 
      suppressor. With UV detection, iodate exhibited satisfactory linearity in the 
      range of 0.1-10.0 mg/L with a correlation coefficient of 0.9996. The detection 
      limit (LOD) was 45.53 mug/L, based on the signal-to-noise ratio of 3 (S/N=3) and a 
      100 muL injection volume. Relative standard deviations (RSDs) for retention time, 
      peak area and peak height were all less than 2.1%. Recoveries of added iodate 
      were in the range of 98.4-101.6% for the spiked samples. The quantitative 
      determination of iodate in edible salt was accomplished by this column-switching 
      technique, without any pretreatment and interference. The results on six samples 
      were statistically compared with results determined by conventional titrimetric 
      method.
