提高溶液pH,采用高电流密度强化镍电解生产已在国内获得成功。为了获得合格牌号的阴极产物,研究微量杂质放电的电化学行为,具有一定的现实意义。 在简单的硫酸盐或氯化物体系中,微量杂质放电的电化学行为,已有较多的文献报导,但在提高溶液pH后和在高电流密度下沉积镍时微量杂质的电化学行为,尚未见有文献报导。 Improve the solution pH, the use of high current density enhanced nickel electrolysis production has been successful in the country. In order to obtain the qualified cathode product, it is of practical significance to study the electrochemical behavior of micro-impurity discharge. The electrochemical behavior of trace impurities in simple sulfate or chloride systems has been reported in the literature, but the electrochemical behavior of trace impurities when nickel is deposited at elevated pH and at high current densities has not been See literature reports.
