Основными минусами их применения служит высокая стоимость, а также тот факт, что по своей природе они могут быть токсичными. Вследствие этого возникла потребность в поиске новых безопасных, дешевых и эффективных ингибиторов коррозии. В данный список можно включить лекарственные препараты, которые могут выступать потенциальными ингибиторами вследствие присутствия в их структуре атомов азота, серы и т.п. В работе изучена возможность применения просроченного лекарственного препарата Дротаверина в качестве ингибитора коррозии углеродистой стали в 0,5 М H2SO4. Концентрация препарата составляла 20…80 мг/л. Методами гравиметрии, сканирующей электронной микроскопии (СЭМ), потенциодинамической поляризации, электрохимической диффузии и импедансной спектроскопии была установлена наиболее эффективная концентрация Дротаверина – 80 мг/л, которой соответствовал защитный эффект 95%. Все исследования проводились при комнатной температуре. Уменьшение емкости двойного электрического слоя в присутствии ингибитора свидетельствует об адсорбции компонентов лекарства на металлической поверхности. Результаты поляризационных измерений показали, что Дротаверин является ингибитором смешанного типа. Анализ состояния металлической поверхности посредством сканирующего электронного микроскопа после воздействия на неё ингибированного раствора позволяет судить о высокой защитной эффективности Дротаверина в наивысшей исследуемой концентрации.</p></abstract><trans-abstract xml:lang="en"><p>It is known that organic compounds are the most effective corrosion inhibitors. The main disadvantages of their use are the high cost, as well as the fact that by their nature they can be toxic. As a result there was a need to find new safe, cheap and effective corrosion inhibitors. This list can include drugs that can act as potential inhibitors due to the presence of nitrogen, sulfur, etc. atoms in their structure. The paper examines the possibility of using the expired drug Drotaverine as a corrosion inhibitor of carbon steel in 0.5 M H2SO4. The concentration of the drug was 20…80 mg/l – Gravimetry, scanning electron microscopy (SEM), potentiodynamic polarization, electrochemical diffusion and impedance spectroscopy were used to determine the most effective concentration of Drotaverine – 80 mg/l, which corresponded to a protective effect of 95%. All studies were conducted at room temperature. A decrease in the capacity of the double electric layer in the presence of an inhibitor indicates the adsorption of the drug components on the metal surface. The results of polarization measurements showed that Drotaverine is a mixed-type inhibitor. Analysis of the state of the metal surface by means of a scanning electron microscope after exposure to an inhibited solution allows us to judge the high protective effectiveness of Drotaverine in the highest concentration under study.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>просроченные лекарственные препараты</kwd><kwd>углеродистая сталь</kwd><kwd>коррозия</kwd><kwd>Дротаверин</kwd><kwd>защитная эффективность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>еxpired drugs</kwd><kwd>carbon steel</kwd><kwd>corrosion</kwd><kwd>Drotaverinе</kwd><kwd>protective efficiency</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Результаты получены с использованием оснащения Центра коллективного пользования научным оборудованием ТГУ имени Г.Р.
