Установлено, что сурьма, в отличие от германия и олова, в определенных условиях способствует увеличению выхода цинка по току. Обусловлено это тем, что в процессе электролиза на отдельных участках катода осаждается сплав цинка с сурьмой, обладающий более положительным, чем цинк, потенциалом, в результате чего разряд ионов цинка протекает в режиме деполяризации с более высоким выходом по току. Снижение выхода по току цинка при доле сурьмы более 0,2 мг/л связано с превалированием действия гальванических пар сурьмы с цинком над электролизом с деполяризацией. Установлено, что сурьма усиливает отрицательное влияние кобальта на выход по току цинка вследствие образования сплава кобальта с сурьмой, на котором перенапряжение выделения водорода меньше, чем на цинке.</p></abstract><trans-abstract xml:lang="en"><p>The influence of antimony ions (Sb3+) in a concentration range of 0,001–0,200 mg/L on the current yield of zinc during the electrolysis of sulfate solutions is investigated. It is established that antimony, in contrast to germanium and tin, promotes an increase in current yield of zinc under definite conditions. This is caused by the fact that the alloy of zinc with antimony, which possesses the potential more positive compared with zinc, is deposited on separate cathode segments, due to which, the discharge of zinc ions proceeds in the depolarization mode with a higher current yield. A decrease in the current yield of zinc with the fraction of antimony higher than 0,2 mg/L is associated with the prevalent effect of galvanic pairs of antimony with zinc over the electrolysis with the depolarization. It is established that antimony enhances the negative effect of cobalt on the current yield of zinc due to the formation of the alloy of cobalt with antimony, on which the isolation overvoltage of hydrogen is lower than on zinc.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>электролиз цинка</kwd><kwd>выход по току цинка</kwd><kwd>сурьма и ее сплавы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>electrolysis of zinc</kwd><kwd>current yield of zinc</kwd><kwd>antimony and its alloys</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">Loskutov F.M.
