摘要
介绍了用有机酸 (Ar(OH) 3COOH)从废定影液中还原银的方法及工艺条件。试验结果表明 ,用有机酸 (Ar(OH) 3COOH)从废定影液中还原银 ,银还原率为 99 2 0 % ,总回收率为 94 5 % ,回收的银粉 (片 )中银的质量分数为 97 43%
Recovery of silver from spent fixing bath with organic acid (Ar(OH) 3COOH) are investigated.The results show that Ag in spent fixing bath can be reduced effectively by the organic acid.Reduction rate and total recovery are 99.20% and 94.44%,respectively.
