Abstract
Способ подготовки поверхности индикаторного электрода для вольтамперометрического анализа, включайщий электрохимическую обработку поверхности электрода при переменном токе, отличающийся тем, что подложку индикаторного электрода помещают в анодную камеру мембранного электролизера, заполненную 0,05 М раствором хлорида калия через которую с помощью индифферентных электродов пропускают переменный ток с амплитудой 0,45-0,5 A в течение 3 мин, затем помещают в раствор нитрата закиси ртути (I) и проводят электролиз при постоянном токе 20 мА в течение 1 мин, потом ртутно-пленочный электрод ополаскивают бидистиллированной водой и помещают в анодную камеру мембранного электролизера, заполненную 0,05 М KCl через которую с помощью индикаторных электродов пропускают переменный электрический ток частотой 50 Гц с амплитудой 0,45-0,5 A в течение 6 мин. A method for preparing the surface of an indicator electrode for voltammetric analysis, including electrochemical treatment of the electrode surface at alternating current, characterized in that the indicator electrode substrate is placed in the anode chamber of a membrane electrolyzer filled with a 0.05 M solution of potassium chloride, through which an alternating current is passed with the help of indifferent electrodes. amplitude of 0.45-0.5 A for 3 min, then placed in a solution of mercuric oxide (I) nitrate and electrolysis is carried out at a constant current of 20 mA for 1 min, then the mercury-film electrode is rinsed with bidistilled water and placed in the anode chamber membrane electrolyzer filled with 0.05 M KCl through which, using indicator electrodes, an alternating electric current with a frequency of 50 Hz and an amplitude of 0.45-0.5 A is passed for 6 minutes.
