Abstract

The iodione in infant formula is extracted with water, and proteins are precipitated using potassium ferrocyanide and zinc acetate. Then got sample clarified by filtration. By Sample solutions were measured with the inductively coupled plasma mass spectrometry (ICP-MS), which the ¹³⁰Te as an internal standard for quantitative analysis. This method is simple and fast, with which the detection limit is 0.10 mg/kg, the recovery rate is 90.8%～109%, the correlation coefficients is over 0.999, and the precision (RSD) is less than 2%.
