Separation was achieved on a laboratory-made capillary column (100mm×0.32mm i.d.) packed with silica gel, followed by modification with 20mM hexadimethrine bromide. Sodium perchlorate-methanol (95:5, v/v) was used as the eluent and analyte anions were detected at 225nm. Iodate, bromate, nitrate, iodide and thiocyanate were eluted within 8min, with relative standard deviations of the retention time, peak area and peak height smaller than 2.4%. Effects of the eluent composition on the retention behavior were also investigated. The limit of detection (S/N=3) of iodide was 6.5μgL−1, whereas that of thiocyanate was 16.2μgL−1. The method was successfully applied to the rapid and direct determination of iodide in powdered milk and thiocyanate in human saliva without any pre-concentration. The modified column could be used for about 1 month (8h operation per day) without loss of hexadimethrine bromide.
