   <abstract xml:lang="ru">
    <p>В работе рассмотрено электрохимическое поведение адреналина и дофамина в гидрогелевых средах на основе гуаровой камеди и полиакриламида с использованием графитовых электродов, модифицированных поли(толуидиновым синим). Методом циклической вольтамперометрии проведена оценка диффузии катехоламинов в гидрогелях различного состава. Обнаружено, что исследованные гелеобразователи существенно влияют на электрохимические превращения в системе «поли(толуидиновый синий)-катехоламины». Показано, что результирующие характеристики ЦВА определяются не только электрохимическими превращениями адреналина и дофамина на поверхности электрода, но и физико-химическими свойствами гидрогелеобразователя. Отмечено микроконцентрирующее действие гидрогеля, что в ряде случаев позволяет регистрировать пиковые значения силы тока в несколько раз выше, чем в водной среде. Присутствие на электроде гидрогеля способствует более полной регистрации редокс-превращений катехоламинов и их метаболитов. Адреналин и дофамин обладают разными диффузионными и адсорбционными свойствами в отношении гуаровой камеди и полиакриламида, что отражается количественными и качественными различиями кривых ЦВА.</p>

   <trans-abstract xml:lang="en">
    <p>Electrochemical behavior of adrenaline and dopamine in hydrogel guar gum and polyacrylamide media was shown in the research. Graphite electrodes modified by (poly)toluidine blue were used. We evaluated diffusion of catecholamines in hydrogels using cyclic voltammetry (CVA) method. It was identified interaction between the hydrogel medium and a system &quot;dye-a catecholamine&quot;. It was shown that physical and chemical properties of hydrogel affect the characteristics of cyclic voltammetry as well as the electrochemical transformations of adrenaline and dopamine. It was marked microconcentric action of the hydrogel. In some cases it allows to record higher peak value of the current than in the aquatic environment. The presence of hydrogel on the electrode contributes to a more complete registration of redox transformations of catecholamines and their metabolites. The CVA curves have quantitative and qualitative differences because of different diffusion and adsorption properties of adrenaline and dopamine in such medium.</p>
