ADSORBENT FOR ELIMINATING HARMFUL IONS USING IRON-LOADED SLUDGE AND METHOD FOR PRODUCING THE SAME

摘要

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.
