A feasible chromatographic method for the determination of iodide using ion chromatography (IC) with series bulk acoustic wave (SBAW) detection has been developed. The advantages of the good selectivity of ion chromatography and the highly sensitive response of SBAW have been combined to improve detection limit, linearity, and reproducibility. The detection limit has been estimated to be 5 ng/ml. For the IC analysis a 12.5-μm polymethacrylate resin column incorporating a quaternary base was used, with the mobile phase being 5.0 mMphthalic acid. The method has been applied to the determination of iodide in some dairy products and table salt.
