چکیده
본 연구에서는 물리적 선별기술을 이용하여 폐금속광산 주변의 중금속으로 오염된 토양 모사체를 처리하고자 하였다. 자력선별을 적용한 경우 5,000gauss 이상의 조건에서 평균적으로 납 53%, 아연 67%, 비소 66%, 카드뮴 71%의 제거율을 보이며 부피를 약 16% 감소시켰다. 코로나 방전형 정전선별 적용 시 공급전압에 따른 살펴본 결과, 납은 –35kV일 때 38%, 아연과 카드뮴의 –30kV일 각각 45%와 48%, 비소는 –25kV 38%로 가장 높았다. 하지만 비용적인 부분과 추후 처리해야 할 오염 토양의 고려할 –10kV 조건이 최적이라 사료된다.

Leachability of Arsenic and Heavy Metals from Mine Tailings of Abandoned Metal Mines
Mine tailings from an abandoned metal mine in Korea contained high concentrations of arsenic (As) and heavy metals [e.g., As: 67,336, Fe: 137,180, Cu: 764, Pb: 3,572, and Zn: 12,420 (mg/kg)]. US EPA method 6010 was an effective method for analyzing total arsenic and heavy metals concentrations. Arsenic in the mine tailings showed a high residual fraction of 89% by a sequential extraction. In To...

متن کاملRemoval of Heavy Metal from Contaminated Soil with Chelating Agents
Removal of copper and nickel by the addition of the biodegradable chelating agent, chitosan and ethylenediamine tetraacetic acid (EDTA), was investigated, alongside the reaction of a reference compound sodium citrate for comparison. The artificial-contaminated soils were used in this study. The experiments showed that the extraction ability for copper and nickel from the contaminated soil decre...
متن کاملRemediation of soil contaminated with the heavy metal (Cd2+).
Soil contamination by heavy metals is increasing. The biosorption process for removal of the heavy metal Cd(2+) from contaminated soil is chosen for this study due to its economy, commercial applications, and because it acts without destroying soil structure. The study is divided into four parts (1) soil leaching: the relationships between the soil leaching effect and agitation rates, solvent c...
