一种含钯物料中钯的回收

Recovery of Palladium from a Palladium Material

对传统的氯化铵法回收钯工艺进行了改进，采用添加氧化剂的方式将钯调整为Pd（Ⅳ）形态，控制加入盐酸的速度，减少钯在尾液中的量，使钯的回收率达到98.5%以上。

The traditional method of ammonium chloride recovery of palladium process was improved. By adding oxidant palladium adjusted to Pd（IV） morphology, and speed of adding HCl was slowed down to reduce Pd content in tail solution. The recovery rate palladium reached 98.5%.
