Abstract

The objective of this study was to investigate mineral precipitates, which derived from the zero valent iron (ZVI) corrosion during TCE dechlorination and to find the controlling factors in mineral precipitates. A series of column experiemnts were conducted to evaluate the location of ZVI and the effects of electrode arrangements in electro-enhanced permeable reactive barrier (E2PRB) systems. Based on mineralogical study, ZVI samples near the influent port had more lepidocrocite, ferrihydrite or Fe (oxy)hydroxide, and (phospho)siderite while backward samples had more akaganeite, magnetite/maghemite, and intermediate green rust (GR) I and GR II. A suite of mineral distribution was preferabley related to the dissolved oxygen and the increased pH. Controlling factors of mineral precipitates in an E2PRB system were found to be (1) pH, (2) dissolved oxygen, (3) the types of Fe intermediates, and (4) anionic species to form complex strongly.

본 연구는 0가 철 (ZVI)의 설치위치와 전극의 배열에 따른 다양한 조합의 전기적 투수성 반응벽을 대상으로 트리클로로에틸렌의 탈염소화 반응에 의한 정화시 ZVI의 부식에 기인하는 광물상침전물에 대해 알아보고, 이에 대한 조절 요소를 알아보고자 한다. 광물학적 연구 결과, 지하수 유입부의 ZVI 시료는 상대적으로 많은 레피도크로사이트, 훼리하이드라이트 혹은 철 수산화물과 (phospho)siderite가 산출되는 반면, 용출부의 ZVI 시료는 아카가나이트, 자철석/마그헤마이트, 그리고 중간 산물인 green rust (CR) I 과 CR II가 산출되었다. 이러한 광물 조합의 변화는 용존 산소 및 pH의 상승에 주로 기인한 것으로 나타났다. 또한 전기적 투수성 반응벽 내에 산출되는 광물상 침전물들의 조절 요소들은 (1) pH, (2) 용존산소, (3) 철의 부식시 중간 산물, (4) 음이온 종류 등으로 밝혀졌다.
