Abstract:A new method for retrieval of silver from photographic fixers. The reduction process is directed to transform silver from its chloride by using ascorbic acid. This process can be fast at pH above 9 and be completed in a short time with the ammonia in low concentration.
Keywords:silver  recovery  silver chloride  ascorbic acid  reduction
