摘　　要：本文介绍了一种利用纳米钯捕集剂从银阳极泥硝浸液中直接回收钯的生产工艺。研究结果表明,将硝浸液酸浓控制在10%左右,按照硝浸液中钯总量的3倍添加纳米药剂,钯的直收率可达95%。This paper introduced a new process of recovering palladium from the leaching solution of silver anode slime with nanometer palladium collector.The results showed that the direct yield of palladium could reach above 95%by controlling the acid concentration of the leaching solution at about 10%and adding nano agents in accordance with three times of the total amount of palladium in the leaching solution.

关 键 词：纳米 钯捕集 直收率
