Abstract: An ion chromatography - voltammetry (single potential) method by using China instrumentwas developed for the rapid determination of iodide (I-) and thiocyanate (SCN-) with detection limits: 1.9 mg/L , 4.7 mg/L, reproducibility (RSD %, n = 3): 1.12% , 1.58%, accuracy (recovery): 98.3%, 93.6% respectively. The concentration (I-): 2.013mg/L, (SCN-): 0.109mg/Lin milk were detected in 5minutes. The method showed higher sensitivity, better accuracy and shorter analytical period, and would be applied to milk routine analysis.
Key words: ion chromatography, voltammetry, single potential, iodide, thiocyanate
