Two species of iodine, i.e. iodide and iodate in commercial iodized salt were determined using ion pair HPLC. From 15 samples analysed, the iodide and iodate content ranged from 24,05 ± 2,51 to 70,25 ± 3,78 ppm and from 31,43 ± 8,10 to 87,59 ± 0,44 ppm, respectively. The method used was found satisfactory in terms of precission, accuracy, sensitivity and selectivity, therefore the method seem acceptable for the determination of iodide and iodate content in iodized salt samples.
