从废液中回收银的研究

为了寻求从银废液中回收银的有效方法，对硫化钠从废定影液中回收银和用金属直接还原氯化银的实验方法进行了研究，得到优化的实验条件，并从电极电势的过程进行了理论探讨．结果表明，此二种方法在实际应用中有一定价值

Study on Retrieval of Silver from Waste Liquid

To look for an effective way of retrieving of silver from silver waste liquid, the study was done on the way of recovery of silver from easte fixing bath under the action of sodium sulphide and the way of mental directly reducing silver oxide and good experiment condition was got and it was approached from the observation of electropotential. The result proved: these two methods are valuable in practical use.
