[A potentiometric determination of iodide in milk by use of the iron--selective electrode (author's transl)].

A method for quantitative determination of iodide in milk by use of the ion-selective electrode is described. The proposed method is rapid and simple. No sample pretreatment is required exept for sample ionic strength adjustment. It was possible to determine iodide concentrations down to 40 microgram/l with average relative standard deviation of 3,4%. The concentration of iodide in milk samples determined by this method ranged from 61,5 microgram J-/l to 190,8 microgram J-/l.
