摘要
用盐酸一氧化钠溶液选择性从含Ｐｄ废催化剂中浸出Ｐｄ，控制浸出液中Ａｌ离子浓度，用Ｆｅ置换法富集Ｐｄ。本工艺已用实际生产。
Palladium was extracted from used Al 2 O 3 support catalysts by using the selective leaching with HCl NaClO 3 , and then cementated palladium from the leaching solution with Fe under the controlling the concentration of Al(Ⅲ) in the solution. This technique has been used in industry.
