摘　　要：用硫酸溶解载体—盐酸＋氧化剂浸出—离子交换提取３１－１Ａ催化剂（含Ｐｄ０．０３１％）中的钯，可获得纯度９９．９７％Ｐｄ产品，实收率＞９７％。A new process to recover palladium from wasted catalyst by using H 2SO 4 dissolving carrier — HCl leaching with an oxidant — ion exchanging was described. Over 99 97% purity of palladium can be obtained by reduction refining and the recovery can be up to 97%.
