Abstract

PVC-Al(OH)3 beads were prepared to remove arsenic (As) ions using aluminium hydroxide sludgefor an effective re-use. The sludge was obtained from domestic treatment facilities of acid mine drainages. The absorption behavior of arsenic ion was investigated in the pH range within 2 and 12. As a result, the removal efficiencies of As(V) ion were higher than that of As(III), over the entire pH range of this study. The removal efficiencies of As(V) ion increased to 100% at neutral pHs within 500 min of reaction duration. The efficiencies were low at pH 2 and pH 12, because of the high dissolution of aluminum hydroxide at those pHs. The absorbed amount of As(V) ions increased to 200 mmol/g at 200 mmol/L initial As concentration.

국내 산성광산배수 처리장에서 회수된 수산화알루미늄 슬러지를 효율적으로 활용하기 위해서 폴리염화비닐 (PVC)과 혼합해 PVC-Al(OH)3 비드를 제조하고 비소 이온 제거를 위해 사용하고자 하였다. pH를 2에서 12로 변화시키며 비소이온의 흡착거동을 조사한 결과 모든 구간에서 비소 5가 이온의 제거율이 비소 3가 이온보다 높았으며, pH가 중성영역에서 제거율은 500 분 내에 100%를 나타냈다. 비소 제거율은 pH가 2와 12에서 감소하였는데, 이는 수산화알루미늄이 이 영역에서 용해되는 것이 원인으로 분석되었다. 비소 5가 이온의 경우 초기 농도 200 mmol/L일 때 흡착량은 200 mmol/g까지 증가하였다.
