For evaluation of adsorption characteristics of heavy metals, precipitates were collected from stream bottom in the Dalseong mine. The removal of some heavy metals such as As, Cu, and Cd from aqueous solution is studied using a precipitates taken from acid mine drainage. The yellowish brown (Munsell...

흡착 실험 결과 대부분의 시료에서 수용액의 농도에 관계없이 무엇이 우선적으로 제거되었는가? | 0 사이의 범위에서는 레피도크로사이트(lepidocrocite)를 포함하고 있다. 흡착 실험 결과 대부분의 시료에서 수용액의 농도에 관계없이 As가 우선적으로 제거되었으며, pH 6.0에서 1시간 동안 반응하여 합성한 철 산화/수산화물이 가장 좋은 As를 제거 효율을 나타내었다. | |
중금속 흡착에 미치는 주된 요인은 무엇인가? | 중금속 흡착에 미치는 주된 요인은 중금속의 초기 농도, 용액의 pH 변화, 온도의 변화, 흡착제의 성질, 경쟁 이온 및 리간드 등, 각 조건 또는 복합 조건에서 중금속 흡착에 미치는 영향 등은 많은 연구자들에 의해 연구되었다(Basta and Tabatabai, 1992; Harter, 1992; Peters and Shem, 1992; Gao et al., 1997). | |
