Abstract: The present invention relates to an adsorbent for eliminating harmful ions using iron sludge and a method for producing the same, more specifically, to an absorbent which is simply obtained by removing impurities from iron sludge, a byproduct from a mine water drainage process, and drying and crushing the iron sludge. The adsorbent obtained by the method of the present invention can effectively remove harmful ions including arsenic ions, fluorine ions, and selenium ions, and can enable users to easily detach the ions from the absorbent by adding hydroxyl ions for reuse. Also the user can recycle the iron sludge which is discarded as the byproduct from a mine water drainage process for reducing the production costs of the absorbent and offering an environmentally friendly effect.

Abstract: 본발명은 3가철을이용한중금속으로오염된토양의세척방법에관한것이다. 종래에중금속으로오염된토양을무기산으로세척하면토양광물의용해및 처리토의산성화를초래하는문제점이있었다. 본발명은이를보완하기위하여토양에덜 유해하고, 비교적안전한 3가철을이용하여납, 구리, 카드뮴, 아연등의중금속으로오염된토양의효과적이고친환경적인세척방법을제공하고자한다.
Abstract translation: 本发明涉及一种利用三价铁洗涤被重金属污染的土壤的方法。 常规问题是，如果用无机酸洗涤被重金属污染的土壤，土壤矿物质的溶解和处理土壤的酸化就会引起。 为了解决这个问题，本发明提供了一种有效和环保的方法，通过使用对土壤有害和相对安全的三价铁来洗涤被重金属（包括铅，铜，镉，锌等）污染的土壤。

Abstract: 본 발명은 비소로 오염된 토양을 효과적으로 정화하기 위한 환원제와 킬레이트를 포함하는 토양세척액 및 이를 이용한 토양 세척 방법에 관한 것이다.
본 발명은 기존의 방법으로 제거가 어려운 토양 중 철/망간 산화물에 강하게 결합되어 있는 비소를 효과적으로 정화할 수 있다. 또한 산세척과 비교하여 강한 산성조건을 요구하지 않기 때문에 토양구조의 파괴나 처리 후 토양의 중화과정이 불필요하며 기존의 킬레이트제를 이용한 세척방법에서 많이 사용되고 있는 EDTA보다 금속과의 결합력이 낮지만 환경적으로 위해성이 적은 oxalate이나 cirate과 같은 킬레이트제를 적용하여 높은 비소의 정화효율을 얻을 수 있어 친환경적인 방법이다.Abstract translation: 本发明涉及包含还原螯合剂和使用其的洗涤方法来有效地补救被砷污染的土壤的污垢清洗溶液。 本发明分离强烈附着于铁/锰氧化物的砷，其中如果使用先前的方法，砷难以除去。 不需要强酸性条件，与酸洗相比，该方法不会经历土壤结构破坏或土壤中和，并且对于通过使用草酸盐或草酸盐等螯合剂能够获得高纯度的砷的净化效果而言是环保的 柠檬酸盐，其与金属的一致性较低，但是比以前在使用螯合剂的洗涤方法中广泛使用的EDTA有害。

Abstract: PURPOSE: An electrokinetic meditation apparatus for anionic contaminants using a sacrificial anode is provided to purify the anionic contaminants in soil polluted with the anionic contaminants without a separate basic electrolyte processing for changing the pH of the entire soil to the basic condition, by removing hydrogen ions generated in an anode. CONSTITUTION: An electrokinetic meditation apparatus for anionic contaminants comprises an anode(20), a cathode(30), an anode electrolyzer(50), and a cathode electrolyzer(52). The anode and cathode are positioned on both sides of soil polluted with the anionic contaminants, and form an electric field on the contaminated soil. An anode-electrolyte and an cathode-electrolyte for supplying electrolytes to the anode and cathode are respectively stored in the anode electrolyzer and cathode electrolyzer, respectively. The anode itself is oxidized and is made of components consisting of the soil. A sacrificial anode is any one selected from iron, aluminum, or their alloys. The sacrificial anode is a bent form or has scratches on the surface. [Reference numerals] (AA) Polluted soil
