Abstract

A method for the determination of iodate was developed by reversed-phase high-performance liquid chromatography with UV detection. Iodate was converted to iodine, which was separated from the matrix using a reversed-phase Ultrasphere C₁₈ column (250 x 4.6 mm, 5 μm) with methanol-1 mmol L^-1 H₃PO₄ (20:80, v/v) as mobile phase at 1.00 mL min^-1 and UV detection at 224 nm. The calibration graph was linear from 0.05 μg mL^-1 to 5.00μg mL^-1 for iodine with a correlation coefficient of 0.9994 (n = 7). The detection limit was 0.01 μg mL^-1. The method was successfully applied to the determination of iodate in iodized salt. The recovery was from 96% to 101% and the relative standard deviation was in the range of 1.5% to 2.9%.
