摘要
提出了一个独特的湿法还原固体氯化银的新方法。在少量氨存在下用化学计量的抗坏血酸溶液还原氯化银，反应迅速，产物纯度高。在ｐＨ９以上１０ｍｉｎ内可还原完全。
An unique reduction process was proposed and tested for recovery of silver from its chloride. The reduction of silver chloride with ascorbic acid in the presence the aid of ammonia in low concentration was found to be fast at pH above 9 and complete recovery of silver is attainable with stoichiometric ascorbic acid within 10 min.
