【摘要】 本文研究了用不溶性阳极电解钴的行为,讨论了电解质的浓度、电流密度与电流效率的关系,也考查了各种金属离子和有机萃取剂对电解钴的影响。实验结果表明:盐酸体系的电流效率比硫酸体系的电流效率高;Zn²⁺、Ni²⁺等金属离子对电解钴的质量有明显的影响;而Mn²⁺离子的存在是无关紧要的,值得注意的是,有机萃取剂对电解的影响是一个很重要的问题。更多还原

【Abstract】 In this paper, the electrolytic behavior of cobalt by non-soluble anode process has been studied. The relationship of electrolyte concentration, current density and current efficiency have been discussed.The influence of foreign metal ions and extractants on current efficiencies have been also examined and discussed. The influences of foreign metalions and extracants on cobalt elec- trolysis have been also examined. The experimental results show that current efficiency in HCL system is higher than in H₂SO₄ system, and that the presence of Zn²⁺, Ni²⁺, ions etc. Affects the electrolytical cobalt quality considerablly but the presence of Mn²⁺ ion has no effect. It should be noted that the influence of organic extrac- tants (P₂₀₄ and N₂₃₅) on electrolysis is a important question.更多还原
