摘要
研究了从废旧电子元件中回收钯的方法 :硝酸溶解—盐酸除银—氧化剂加氯化铵沉淀钯。精制后 ,可获得纯度为 99 95 %的海绵钯 ,钯的回收率不低于 95 %。通过与其它两种工艺比较 ,证明了此工艺的优越性。
A process to recover Pd from spent electronic scraps was studied using material dissolving with HNO 3 by removed with HCl oxidant plus NH 4Cl precipitating Pd followed by reduction of Pd precipitate.The resultant crude Pd can be refined by traditional methods.The purity of Pd is 99.95% and the recovery rate of Pd is over 95%.It advantages are proved by comparing with other two methods.
