- W2334208564 abstract "청양지역 폐광산의 오염원인인 중금속의 제거를 침출과 이온교환법을 활용한 융합공정을 통해 실험하였으며 중금속에 오염된 토양시료는 통계처리를 하여 분석하였다. 오염토양은 일차로 부선처리법으로 분리하였으며, 사용시약이 증가할수록 선별지수는 증가하였다. 중금속을 제거하기 위한 침출과 이온분리법에 의해 선별도는 더 향상이 되었다. 침출속도는 황산용액이 증가할수록 증가되었으며, 침출용액은 이온교환법에 의해 상당부분 제거가 되었다. 침출과 이온교환법이 결합된 연속융합공정을 개발하여 중금속 제거 실험을 하였으며, 향후 개선을 통해 중금속의 제거효과가 향상될 것이며, 이를 통해 폐광산의 오염토양에 적용 가능함을 알 수 있었다. The convergence process utilized both leaching and ion exchange techniques has been investigated for the heavy metals removal in the abandoned mine of Chungyang Province, Korea. The contaminated soil samples by heavy metals from Samkwang mine were analysed by statistical analyses. The highly contaminated soils was initially separated by the flotation process. The selectivity indices were increased with increasing flotation reagents. The selectivity of separation was then improved by the use of both leaching and ion exchange processes in order to extract the heavy metals. The results of this study showed that the higher the sulfuric acid concentration, the leaching rate of heavy metals was increased. The lecheate then was removed by the ion exchange method. The anticipating results might imply that convergence process utilized both leaching and ion exchange techniques would somehow apply for the removal of heavy metals in the abandoned mine." @default.
