Methods: Coulometry Obtained results and novelty: Determinations of IO3- and IO4- in solutions by potentiostatic coulometry method with platinum electrode under U=0,25V vs. saturated Ag/AgCl electrode were carried out. Rates of reduction of iodates are higher in 2-2,5 times than rates of reduction of periodates. Reduction passes in solutions to ІО-, but under saturating of solution with nitrogen - to І2. Standard deviations of determination of anions in individual solutions at the concentration range (0.5-5)*10-5 mol/l make up 3-12%. Rate of electrochemical reduction increases following injection of potassium chloride. Coulometric determination of ІО3? and IO4- under joint presence can be carried out with using difference in rates of electrochemical reactions. Field of application: chemical analysis.
