AOAC Official Method 992.24
Iodide is extracted from the sample matrix using acetic acid and homogenization. The amount of iodide is determined using the known addition technique. The difference in electrode potential is calculated from the extracted sample and the addition of a known standard of 1 mg/L. This electrode potential change is converted into an iodide concentration utilizing the linear range of the ion selective electrode.
This method is used to detect the iodized form of iodine, typically added as iodized salt. Testing measures the amount of ions (I-) and reports as iodide.
This method is suitable for iodized salts (KI) as it dissociates into K+ and I-. This method does not detect native iodine in the sample matrix or sources of iodine that would dissociate into anything other than I-.
