Technical data sheet
PrintMethod description
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.
