To develop a method for the determination of hypochlorite, chloride, chlorite, chlorate, and perchlorate ions in solution; to determine the limits of detection and quantitation for ClO−, Cl−, ClO2−, ClO3−, and ClO4− ions; to evaluate the applicability of the developed method and its suitability for disinfectant analysis.</p></sec><sec><title>Methods</title><p>Methods. Ionic chromatography using a conductometric detection system in isocratic elution mode.</p></sec><sec><title>Results</title><p>Results. The method developed for chromatographic determination of chlorine-containing ions can be used to quantify the content of hypochlorite, chloride, chlorite, chlorate, and perchlorate ions. In isocratic elution mode at 7.5 mM NaOH and a flow rate of 0.4 mL/min, the content of chlorine-containing ions can be determined with high sensitivity. The presented method does not require the use of expensive equipment for the ultrasensitive analysis of the studied compounds.</p></sec><sec><title>Conclusions</title><p>Conclusions. A novel method for the simultaneous determination of hypochlorite, chloride, chlorite, chlorate, and perchlorate ions in case of their combined presence is proposed. The technique can be used to carry out routine control of the content of these disinfectant components during use, increasing their effectiveness at the same time as managing associated toxicological risks.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Цели</title><p>Цели. Разработать методику определения гипохлорит-, хлорид-, хлорит-, хлорати перхлорат-ионов при их совместном присутствии в дезинфицирующих средствах. Определить пределы обнаружения и пределы количественного определения ионов ClO−, Cl−, ClO2−, ClO3−, ClO4−. Провести расчеты валидационных параметров разработанной методики, а также оценить ее пригодность для анализа дезинфицирующих средств.</p></sec><sec><title>Методы</title><p>Методы. Ионообменная хроматография с системой кондуктометрического детектирования в изократическом режиме элюирования.</p></sec><sec><title>Результаты</title><p>Результаты. Новая методика хроматографического определения хлорсодержащих ионов позволяет количественно оценить содержание гипохлорит-, хлорид-, хлорит-, хлорат- и перхлорат-ионов при их одновременном нахождении в модельном растворе и в дезинфицирующих средствах. Изократический режим элюирования 7.5 мМ NaOH при скорости движения потока 0.4 мл/мин позволяет с высокой чувствительностью определять ионы, содержащие атом хлора. Разработанная методика не требует использования дорогостоящего оборудования, необходимого для сверхчувствительного анализа исследуемых соединений.</p></sec><sec><title>Выводы</title><p>Выводы. Впервые предложена методика определения гипохлорит-, хлорид-, хлорит-, хлорат- и перхлорат-ионов при совместном присутствии. Ожидается, что разработанная методика позволит проводить рутинный контроль содержания этих компонентов в дезинфицирующих средствах при их практическом использовании, что приведет к повышению эффективности применения дезинфектантов на их основе и снижению возможных токсикологических рисков.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>гипохлорит-ионы</kwd><kwd>хлорид-ионы</kwd><kwd>хлорит-ионы</kwd><kwd>хлорат-ионы</kwd><kwd>перхлорат-ионы</kwd><kwd>ионообменная хроматография</kwd><kwd>дезинфицирующие средства</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hypochlorite ion</kwd><kwd>chloride ion</kwd><kwd>chlorite ion</kwd><kwd>chlorate ion</kwd><kwd>perchlorate ion</kwd><kwd>ionic chromatography</kwd><kwd>disinfectants</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">McCarthy W.P., O’Callaghan T.F., Danahar M., Gleeson D., O’Connor C., Fenelon M.A., et al.
