Показано влияние различных факторов на катодный сигнал красителя: pH, значения времени накопления и скорости развертки потенциала. Выбраны рабочие условия определения кармуазина в модельных средах: pH = 1,65; Eнак = - 0,1 В, tнак = 10 с; W = 100 мВ/с. Линейная зависимость тока электровосстановления красителя от его концентрации при потенциале -0,15 В наблюдалась в интервале 0,05 -0,5 мг/л, предел обнаружения кармуазина составил 0,02 мг/л. Проведено сравнительное определение кармуазина в безалкогольных напитках вольтамперометрическим и спектрофотометрическим методами.</p></abstract><trans-abstract xml:lang="en"><p>Voltmammetry is used to study electrochemical behavior of Carmoisine (synthetic red food dye from azo dye group) on a glassy carbon electrode. Different factors affect the cathode signal of the dye: pH, potential and accumulation time, and the sweep rate of the potential. We specified working conditions for Carmoisine determination in model solutions: pH = 1.65, Eacc = -0.1V, tacc =10 sec, W =100mV/sec. Linear dependence of Carmoisine electroreduction current on the dye concentration at a potential value of 0.15 V is observed in the range of 0.05 - 0.5 mg/liter. Carmoisine detection limit is 0.02 mg/liter. Results of comparative determination of carmoisine in soft drinks using voltammetric and spectrophotometric techniques are presented.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>azo dyes</kwd><kwd>carmoisine</kwd><kwd>voltammetry</kwd><kwd>spectrophotometry</kwd><kwd>soft drinks</kwd><kwd>азокрасители</kwd><kwd>кармуазин</kwd><kwd>вольтамперометрия</kwd><kwd>спектрофотометрия</kwd><kwd>безалкогольные напитки</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">Chandra U., Gilbert O., Kumara Swamy B.
