Cationic surfactants are one of the classes of substances most commonly used in disinfectants. The trend in recent years has been the use of mixtures of several biocides, which poses new challenges for analytical chemistry. In this study, we describe a method for simultaneous determination in the disinfectants alkyldimethylbenzylammonium chloride (ADBAC), alkyldimethyl(ethylbenzyl)ammonium chloride (ADEBAC), chlorhexidine bigluconate (CHG), and polyhexamethylene biguanide hydrochloride (PHMB).</p></sec><sec><title>Methods</title><p>Methods. The proposed method is based on the use of reverse-phase and hydrophilic high-performance liquid chromatography with diode-array detection</p></sec><sec><title>Results</title><p>Results. The best separation of ADBAC, ADEBAC, and CHG was achieved using a column filled with modified spherical silica gel (5 цт, 4.6 × 250 mm) in gradient elution mode. Acetonitrile and acetate buffer with a pH of 5.4 were used as eluents at a flow rate of 1 ml/min. For the determination of PHMB in the presence of the substances under consideration, hydrophilic high performance liquid chromatography was used. The best separation was achieved on an amine phase column (5 цт, 4.6 × 250 mm) using the same eluents. To determine all the substances under consideration, a diode array detector was used. 3D chromatograms were recorded in the wavelength range from 190 to 400 nm.</p></sec><sec><title>Conclusions</title><p>Conclusions. We have shown that the result of the analysis does not depend on the ratio of cationic surfactants in disinfectants. There is also no influence of N,N-bis-(3-aminopropyl)-dodecylamine (Triamine, TA) and the components most commonly used for the manufacture of disinfectants, which was confirmed by testing the method for analyzing real objects. The linearity range for ADBAC was from 0.0062 to 0.97%, for ADEBAC from 0.000726 to 0.201%, for CHG from 0.0128 to 0.111%, and for PHMB from 0.00311 to 0.0205%. The calculated relative errorfor all determined substances was about 4%.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Цели</title><p>Цели. Катионные поверхностно-активные вещества являются одним из классов веществ, наиболее часто использующихся в качестве активнодействующих в дезинфицирующих средствах. Тенденцией последних лет является использование смесей нескольких биоцидов, что ставит новые задачи перед аналитической химией. В этой работе описан метод для определения при совместном присутствии в дезинфицирующих средствах алкилдиметилбензиламмоний хлорида (АДБАХ), алкилдиметил (этилбензил)аммоний хлорида (АДЭБАХ), хлоргек-сидина биглюконата (ХГБГ) и полигексаметиленбигуанид гидрохлорида (ПГМБ).</p></sec><sec><title>Методы</title><p>Методы. Предложенный метод основан на применении обращенно-фазовой и идрофильной высокоэффективной жидкостной хроматографии с диодно-матричным детектированием.</p></sec><sec><title>Результаты</title><p>Результаты. Наилучшее разделение АДБАХ, АДЭБАХ и ХГБГ было достигнуто при использовании колонки, заполненной модифицированным сферическим силикагелем (5 мкм, 4.6 × 250 мм) в режиме градиентного элюирования. В качестве элюентов использовали ацетонитрил и ацетатный буфер с рН 5.4 при скорости потока 1 мл/мин. Для определения ПГМБ в присутствии рассматриваемых веществ была использована гидрофильная высокоэффективная жидкостная хроматография. Наилучшее разделение было достигнуто на аминофсзной колонке (5 мкм, 4.6 × 250 мм) при использовании тех же элюентов. Для определения всех рассматриваемых веществ использовали диодно-матричный детектор. 3D хроматограммы регистрировали в диапазоне длин волн от 190 до 400 нм</p></sec><sec><title>Выводы</title><p>Выводы. Проведенные исследования показали, что результат анализа не зависит от соотношения катионных поверхностно-активных: веществ в дезинфицирующих средствах. Также отсутствует влияние N,N-бис(3-смlинопропил) додецилсмина (Триамин TA) и наиболее часто используемых для изготовления дезинфицирующих средств компонентов, что было подтверждено при апробации метода для анализа реальных объектов. Диапазон линейности для АДБАХ составил от 0.0062 до 0.97 %, для АДЭБАХ - от 0.000726 до 0.201 %, для ХГБГ – от 0.0128 до 0.111 %, для ПГМБ - от 0.00311 до 0.0205 %. Рассчитанная относительная погрешность для всех определяемых: веществ составила около 4 %.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>алкилдиметилбензиламмоний хлорид</kwd><kwd>алкилдиметил (этилбензил)-аммоний хлорид</kwd><kwd>хлоргексидина биглюконат</kwd><kwd>полигексаметиленбигуанид гидрохлорид</kwd><kwd>катионные ПАВ</kwd><kwd>дезинфицирующие средства</kwd><kwd>высокоэффективная жидкостная хроматография</kwd></kwd-group><kwd-group xml:lang="en"><kwd>alkyldimethylbenzylammonium chloride</kwd><kwd>alkyldimethyl(ethylbenzyl)ammonium chloride</kwd><kwd>chlorhexidine digluconate</kwd><kwd>polyhexamethylene biguanide hydrochloride</kwd><kwd>cationic surfactants</kwd><kwd>disinfectants</kwd><kwd>high performance liquid chromatography</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена за счет средств государственного бюджета Российской Федерации в рамках программы научных исследований на 2016-2021 годы (№ 116020550032)</funding-statement><funding-statement xml:lang="en">This work was carried out withfinancial support from the State Budget of the Russian Federation within the Program of Scientific Research for 2016-2021 (No. 116020550032)</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Караев А.Л., Бидёвкина М.В., Фёдорова Л.С., Исаева Е.Е., Алексеева Ж.П.
