T.Oishi等考察了用氨-硫酸铵和氯化铵体系从废印刷线路板中回收铜过程中杂质的行为,并比较了这2个体系的特点。用含铜氨络离子的溶液作氧化剂浸出印刷线路板,铜被选择性溶解,但浸出液中 T. Oishi et al. Investigated the behavior of copper impurities recovered from spent printed circuit boards using ammonia-ammonium sulfate and ammonium chloride systems and compared the characteristics of these two systems. Copper-containing ammonia complex ion solution as the leaching of the printed circuit board, copper is selectively dissolved, but the leachate
