Предложенная методика электрофоретического определения ММА характеризуется высокой точностью результатов, небольшим временем анализа и минимальной пробоподготовкой. Найдены оптимальные условия анализа: концентрация ПАВ (додецилсульфата натрия) — 80 ммоль/л, напряжение, прикладываемое к капилляру, — 25 кВ, температура — 25 °C. Разработанная методика апробирована при анализе реальных объектов из стоматологической практики — базисных материалов, предназначенных для изготовления и перебазировки ортопедических конструкций. Мониторинг высвобождения ММА из образцов ПММА позволил оценить содержание остаточного мономера в деионизованной воде и имитирующей слюну жидкости: после 48 ч концентрация ММА в модельном растворе на 35 % меньше, чем в воде. При прямом спектрофотометрическом детектировании (λ = 215 нм) предел обнаружения ММА в деионизированной воде и имитирующей слюну жидкости составляет 0,015 и 0,020 мкг/мл соответственно.</p></abstract><trans-abstract xml:lang="en"><p>The development of an accessible procedure for determining methyl methacrylate (MMA) in aqueous media is of great interest, since monitoring the content of the residual monomer released from the denture material — polymethyl methacrylate (PMMA) — into the oral cavity in neccesary prostheses. The proposed technique of electrophoretic determination of MMA is characterized by high precision, short analysis time, and minimal sample preparation. Optimal analysis conditions have been found: the concentration of surfactant (sodium dodecyl sulfate) — 80 mmol/liter, capillary voltage — 25 kV, temperature — 25°C. The developed procedure was tested in the analysis of real samples from dental practice: base materials intended for the fabrication and relocation of orthopedic constructions. Monitoring of MMA releasing from PMMA samples allowed to evaluate the residual monomer content in deionized water and artificial saliva: after 48 hours, MMA concentration in model solution is 35% lower than in water. With direct spectrophotometric detection (λ = 215 nm), the limit of detection of MMA in deionized water and artificial saliva is 0.015 and 0.020 μg/ml, respectively.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>метилметакрилат</kwd><kwd>полиметилметакрилат</kwd><kwd>зубной протез</kwd><kwd>капиллярный электрофорез</kwd><kwd>мицеллярная электрокинетическая хроматография</kwd></kwd-group><kwd-group xml:lang="en"><kwd>methyl methacrylate</kwd><kwd>polymethyl methacrylate</kwd><kwd>dentures</kwd><kwd>capillary electrophoresis</kwd><kwd>micellar electrokinetic chromatography</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">Nascimento G.
