用于镀金的柠檬酸金盐

目前,应用最广泛的镀金工艺为酸性和中性镀金,所使用的氰化亚金钾为剧毒品,对工作环境和职工身体健康有较大危害,给操作与管理带来不便。柠檬酸金盐是氰化亚金钾与柠檬酸酸式盐的混合结晶体,其毒性较低,可代替氰化亚金钾用于酸性和中性镀金工艺。文中介绍了柠檬酸金盐的毒性试验结果、生产方法、产品质量指标及使用方法。

Gold citrate salt for gold plating

Now,the most popular processes for gold plating are acidic and neutral gold plating,in which potassium aurous cyanide is widely used.But potassium aurous cyanide is a toxic substance,which has a great harm to workers and the environment,and is hard to use and manage.Gold citrate salt,whose toxicity is lower,is a kind of commixture crystal of potassium aurous cyanide and citrate acidic salt,and can be a substitute for potassium aurous cyanide.This paper introduced the toxicity test results,production methods,quality index and usage of gold citrate salt.
