   Настоящий обзор рассматривает исследования защиты меди и некоторых её сплавов от коррозии ингибиторов коррозии (ИК) класса триазолов преимущественно за последние десять лет. В отличие от многочисленных обзоров, посвященных анализу ингибирующих коррозию свойств 1,2,3-бензотриазола (БТА) и его производных, он посвящен другой большой группе ИК класса триазолов, родоначальником которых является 1Н-1,2,4-триазол (ТА). Большое внимание в этой статье отводится исследованию адсорбции изучаемых ИК из нейтральных водных растворов на поверхности меди. Оно проводилось in situ при постоянном потенциале электрода высокочувствительным методом отражательной эллипсометрии. Это предоставило возможность получить изотермы адсорбции ТА и его производных и вычислить из них величины свободной энергии адсорбции этих соединений на меди.

   This review article examines research of the protection of copper and some of its alloys from corrosion by organic corrosion inhibitors (CIs) of the triazole class, primarily over the past ten years. In contrast to numerous reviews devoted to the analysis of the corrosion-inhibiting properties of 1,2,3-benzotriazole (BTA) and its derivatives, it is devoted to another large group of CIs class triazoles, the parent of which is 1H-1,2,4-triazole (TA). Much attention in this article is given to the study of adsorption of the studied CIs from neutral aqueous solutions on the surface of copper. It was carried out in situ at a constant electrode potential using the highly sensitive method of reflective ellipsometry. This made it possible to obtain adsorption isotherms of TA and its derivatives and to calculate from them the free energy of adsorption of these compounds on copper.
