Novel Absorbents for Trace Extraction Heavy Metals from Water

The present invention discloses the use of ligand modified sorbents which are effective for removal of heavy metals from water that are easy to prepare and are easy to regenerate and recycled at low cost with minimum production of chemical waste byproducts. Such low cost sorbents can find use in applications of metals removal from acid mine water streams from different mining industries, and coal-burning power plants as well as metal-containing waste streams from electroplating and rare metals industries. The present invention includes an apparatus to remove heavy metals from water comprising a heavy metal binding ligand non-chemically attached to a sorbent wherein said heavy metal binding ligand has a first end and a second end and wherein said first end contains a heavy metal binder and wherein said second end contains chemical and structural features for non-chemical binding to said sorbent.
