摘要
研究了利用彩印漂定废液回收废感光胶片中银的方法。废漂定液在pH=8～9时,用KBH4还原回收银,回收银后的漂定液通过补加主要成分可作为浸取剂浸出废感光胶片上的银。该方法银的回收率高,废漂定液可以多次循环使用。
A method to recover silver from waste photographic film with waste fixing bath was studied. Silver in waste fixing bath was reduced by KBH4 in alkali environment （pH = 8 -9 ）. The treated waste fixing bath can be reused by adding some main components and was used to leach silver in the waste photographic film. Recovery rate of silver with this method was high and the waste fixing bath can be recycled.
