В статье приведен анализ литературы по методам получения изотерм адсорбции органических соединений на поверхности металлов из коррозионной среды. Рассмотрены подходы, которые предполагают прямую зависимость между эффективностью ингибирования и степенью покрытия поверхности. В некоторых работах из гравиметрических измерений получают степень покрытия поверхности адсорбатом. Эффективность ингибирования определялась также из сравнения анодных плотностей тока без и в присутствии ингибиторов при их постоянной концентрации. Приведены также примеры использования методов спектроскопии электрохимического импеданса, эллипсометрии, пьезокварцевого микробаланса, теоретических расчетов при анализе адсорбции органических соединений.

This article presents a literature review on methods for obtaining adsorption isotherms for organic compounds on metal surfaces from corrosive environments. Approaches that assume a direct relationship between inhibition efficiency and surface coverage are considered. In some studies, the adsorbate surface coverage is determined from gravimetric measurements. Inhibition efficiency was also determined by comparing anodic current densities with and without inhibitors at a constant concentration. Examples of the use of electrochemical impedance spectroscopy, ellipsometry, piezoelectric quartz microbalance, and theoretical calculations in the analysis of organic compound adsorption are also provided.
