摘　　要：本研究采用湿法工艺回收废钯氧化铝催化剂中的钯,采取无须加热、无须搅拌的常温下浸出新工艺,Pd的浸出率达到99.4%,最终得到纯度99.95%以上的海绵钯粉,钯的回收率达到98.9%。人们以试验为基础,进行了工业化生产。In this study,a wet process was used to recover the palladium in the waste palladium alumina catalyst,and a new process of leaching at room temperature without heating and stirring was adopted,the leaching rate of Pd reached 99.4%,and finally the sponge palladium powder with a purity of more than 99.95% was obtained,and the recovery rate of palladium reached 98.9%.People carried out industrial production based on experiments.
