ABSTRACT:
An adsorbent that can be used to remove environmental contaminants such as organics, cations and anions in a single process step is prepared from humic acid. The adsorbent can be a soluble humic acid in liquid form (e.g., in aqueous solution) or the humic acid can be insolubilized and/or immobilized on a solid support. The adsorbent can also be used to recover agriculturally desirable metals in chelated form from contaminated water. The liquid form of the adsorbent can be used to wash solids to remove contaminants.
