실제 사진폐액에서 은의 회수를 위한 연속순환식 환원 공정을 적용하여 전해시간 및 두 전극간의 전압 차, 농도에 따른 영향을 검토하였다. 희석된 사진폐액에서의 은의 전해효율은 적용전압이 증가하면서 효율이 증가하다가 6V 정도에서 최고의 효율을 보였다. 그러나 그 이상 전압이 증가할수록 은의 회수율은 낮아지는 경향을 보였다. 희석되지 않은 원 사진폐액의 경우에서는 실험조건 하, 전해반응 시 적용 전압이 낮아질수록 효율을 높일 수 있음을 확인하였다.
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
