전기적 환원을 이용한 인공 사진폐수에서의 은 회수를 연속순환식 공정을 적용하여 환원시간 및 두 전극간의 전압 차, 농도유량에 따른 영향을 검토하였다. 은 함유 인공폐수 처리에 있어 적용(인가) 전압과 초기 농도가 증가함에 따라 제거율이 증가함을 보였다. 은 함유 인공폐수의 전해 반응 시, 음극에 환원 석출된 물질의 정성적인 분석을 위해 EPMA 및 XRD 분석 결과, 석출된 물질이 은임을 확인하였다.
Abstract
The influences of reduction time, potential difference and ionic concentration flow rate have been investigated on the electrolytic recovery of silver from artificial photographic wastewater in continuous flow reactor system. As the initial concentration of silver ion and applied potential were increased, the amount of silver recovered was observed to be raised. Also, the electrolytically recovered material from artificial wastewater was proved to be pure silver based on the qualitative analyses by EPMA and XRD.
