Selective Separation of Fe Component from Heavy Metal Mixed Solution Using Coal Fly Ash

摘要

The present invention relates to a method for selectively separating the Fe component from the heavy metal mixed solution using coal ash, and more specifically, to the pH of the heavy metal mixed solution containing Zn and Fe and the amount of coal ash added as an adsorbent and adsorption. The present invention relates to a method for selectively and completely separating only Fe from a heavy metal mixed solution by appropriately adjusting the contact time.
