Abstract
In the continuous flow reductive treatment for recovery of silver from actual photographic wastewater, the effects of electrolysis time, applied potential, and the concentration of silver ion on the process have been examined. The efficiency of silver recovery for diluted photographic wastewater was increased with applied potential and reached its maximum at 6 V. However, the recovery of silver was shown to be decreased with potential above this. When the wastewater was undiluted, the efficiency of silver recovery was observed to rise as the applied potential became lower under the experimental conditions.
