Метод основан на анодном концентрировании иодида в форме иодида ртути Hg2I2 на амальгамированном серебряном индикаторном электроде при потенциале 0,0 В (относительно хлорсеребряного электрода сравнения) с последующей регистрацией пика катодного тока на потенциодинамической вольтамперограмме в водном растворе 0,4 моль/дм3 муравьиной кислоты в интервале потенциалов +0,1 ÷ –0,7 В. Метод применим для определения иодид-ионов в растворе с концентрацией 0,5–100 мкг/дм3; относительное стандартное отклонение (при доверительной вероятности 95 %) снижается с 6,1 до 3,2 % при повышении концентрации иодида от 0,5 до 5,0 мкг/дм3, а в интервале 10–100 мкг/дм3 составляет 2,4–3 %.</p></abstract><trans-abstract xml:lang="en"><p>The possibility to determine iodide ions by stripping voltammetry has been demonstrated in multivitamin preparations against the background of redox active components with a concentration exceeding the iodide content of 600–1000 (ascorbic acid), 8–20 (thiamine, riboflavin), 20–40 (iron ions), 10–12 (manganese ions), 4–6 (copper ions) times. The method is based on the anodic concentration of iodide in the form of mercury iodide Hg2I2 on an amalgamated silver indicator electrode at a potential of 0.0 V (vs. Ag/AgCl reference electrode), followed by recording the cathode current peak in a potentiodynamic voltammogram in 0.4 mol/dm3 formic acid aqueous solution in the range of electrode potential from +0.1 to–0.7 V. The method is applicable for the determination of iodide ions in a solution with 0.5–100 μg/dm3 concentration; the relative standard deviation decreases from 6.1 to 3.2 % with an increase in the concentration of iodide from 0.5 to 5.0 μg/dm3, and in the range of 10–100 μg/dm3 is 2.4–3 %.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>инверсионная вольтамперометрия</kwd><kwd>определение иодида</kwd><kwd>поливитаминные препараты</kwd><kwd>амальгамный электрод</kwd></kwd-group><kwd-group xml:lang="en"><kwd>stripping voltammetry</kwd><kwd>determination of iodide</kwd><kwd>multivitamin preparations</kwd><kwd>amalgam electrode</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Simple and rapid determination of iodide in table salt by stripping potentiometry at a carbon-paste electrode / I.
