| 摘 要： | 应用电解退镀法退除金银复镀层，金镀层和镀层废件中金和银。结果表明，浓硫酸－脂肪醇体系中，最佳退镀条件为电解电压８Ｖ，脂肪醇添加量１５ｇ／ＬＨ２ＳＯ４，搅拌后退镀液呈紊流态，Ｒｅ为２８８０。退镀后金主要存在于固相沉淀物中，其含量在９３％以上，而银存在于固相沉淀物和溶液中，它在两相中的分配比依不同镀层种类而异。

| Abstract: | Electrolytic stripping process for withdrawing gold and silver from cheap scraps plating gold and silver has been conducted. The results showed that in electrolytic bath filled with concentrated H2SO4-glycerine system, the best stripping conditions were as follows: the electrolytic voltage was 8V, amount of glycerine added 15g/LH,so., the Re of electrolytic solution 2880. After electrolytic stripping process, the gold mainly existed in precipitate, and its content was over 93%; the silver accumulated in precipitate or solution, and its distributive ratio was different with kinds of eating. |
