Для расчета величины CeF на основании поляризационных измерений необходимо знать рабочую плотность тока и потенциал (Ei), при котором происходит осаждение металла в соответствующем растворе, а также кинетические параметры выделения водорода для определения парциальной плотности тока водорода (iН2 ) при этом потенциале. С помощью предложенного метода был проведен расчет выхода по току для процессов экстракции никеля и нанесения никелевого покрытия из растворов, содержащих сульфат никеля, при плотности тока 300 А/м2. Определены кинетические параметры выделения водорода по поляризационной кривой, полученной в растворе фонового электролита, содержащем 120 г/л сульфата магния и 18 г/л борной кислоты при рН = 3,9. Получено уравнение для расчета парциальной плотности тока выделения водорода при любом потенциале по кинетическим параметрам. Использование кинетических закономерностей позволило рассчитать CeF никеля в сульфатных растворах разного со- става с рН = 3,0 и 4,1. Рассчитанные значения CeF в пределах статистической погрешности совпали с величиной выхода по току, определенной весовым методом с применением медного кулонометра. Показано, что разделение коммерческого показателя «суммарный выход по току» (CeΣ) на фарадеевский (CeF) и аппаратный (Ceap) в сочетании с использованием метода парциальных поляризационных кривых позволяет получить дополнительную информацию о степени совершенства технологического процесса.</p></abstract><trans-abstract xml:lang="en"><p>The paper considers a method used to determine Faraday current efficiency (CeF) based on the ratio of partial currents of metal and hydrogen reduction. To calculate the Faraday current efficiency based on polarization measurements, it is necessary to know the working current density and potential (Ei) at which the metal is deposited in the corresponding solution, as well as kinetic parameters of hydrogen evolution for determining the partial current density of hydrogen (iН2 ) at this potential. The proposed method was used to calculate current efficiency for the processes of nickel extraction and nickel coating application from solutions containing nickel sulfate at current density of 300 A/m2. The study allowed to determine kinetic parameters of hydrogen evolution by the polarization curve obtained in the background electrolyte solution containing 120 g/l of magnesium sulfate and 18 g/l of boric acid at pH = 3.9. An equation was obtained to calculate the partial current density of hydrogen evolution at any potential by kinetic parameters. The use of kinetic regularities made it possible to calculate nickel CeF in sulphate solutions of different composition and with different pH values (3.0 and 4.1). The calculated CeF values within the margin of error coincide with the current efficiency value determined by the gravimetric method using a copper coulometer. It is shown that the division of the «total current efficiency» (CeΣ), which is a commercial indicator, into Faraday (CeF) and apparatus (Ceap) indicators in combination with the method using partial polarization provide additional information about the degree of process perfection.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>никель</kwd><kwd>электроэкстракция</kwd><kwd>выход по току</kwd><kwd>кинетические параметры</kwd><kwd>парциальные кривые</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nickel</kwd><kwd>electroextraction</kwd><kwd>current efficiency</kwd><kwd>kinetic parameters</kwd><kwd>partial curves</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Plekhanov K., Demin I., Ashikhin V., Koryakin V., Zaikov Yu., Rudoy V., Ostanin N.
