Claims (1)

Способ количественного определения ингибиторов кислотной коррозии в неводных средах, включающий введение пробы с ингибиторами в ячейку для электрохимических испытаний, погружение рабочего, вспомогательного электродов и электрода сравнения в рабочий растворитель, снятие рабочей кривой и определение наличия ингибитора коррозии, отличающийся тем, что электрохимически окисляют азотсодержащие ингибиторы кислотной коррозии до катион-радикалов с отдачей одного электрона, снимают циклическую вольтамперограмму электрохимического окисления ингибиторов кислотной коррозии в пределах от 0 до +2,0 В в деаэрированной среде, замеряют величину анодного пика по току при потенциалах окисления 0,8-1,0 В и определяют концентрацию ингибитора в неводной среде по калибровочному графику.A method for the quantitative determination of acid corrosion inhibitors in non-aqueous media, including introducing a sample with inhibitors into the cell for electrochemical testing, immersing the working, auxiliary and reference electrodes in a working solvent, taking a working curve and determining the presence of a corrosion inhibitor, characterized in that nitrogen-containing inhibitors are electrochemically oxidized acid corrosion to radical cations with the release of one electron, remove the cyclic voltammogram of the electrochemical oxide Acid corrosion inhibitors in the range from 0 to +2.0 V in a deaerated medium, measure the magnitude of the anode peak current at oxidation potentials of 0.8-1.0 V and determine the concentration of the inhibitor in a non-aqueous medium according to the calibration curve.
