The results of a study of the effect of lactic acid on the determination of trace iodide ions by stripping voltammetry (SVA) and potentiometry with ion-selective electrodes are presented. In the latter case, the interference of lactic acid was eliminated by adding 30% ethanol to the test sample, whereas various sample preparation procedures with test sample decomposition were used in SVA.
