Ion-grabbing ligand

A ligand that grabs metal ions so that they can be removed from radioactive wastes

To the inorganic chemist, "ligands" are molecules that stick to other molecules, particularly to metal ions. The resulting "coordination complex" has properties that are usually very different from the ligand or metal alone. This is a picture of a ligand that grabs metal ions so that they can be removed from radioactive wastes.

This work is supported by the National Science Foundation (NSF) Faculty Early Career (CAREER) Development Program (grant CHE 98-74966), and by NSF's Research Experiences for Undergraduates (REU) program (grant CHE 98-20289, awarded to undergraduate Eric Werner). (Date of Image: Unknown)
