Activated carbon adsorption has also been used to remove mercury and other metals from solutions and to clean organic impurities from aqueous feed and wastewater streams. Other adsorbants, such as clays, aluminas, and zeolites, have been used for impurity removal. Ion exchange is widely used in chemical and mining processes for separating one metal from another and for impurity removal.
