Magnetic EDTA: coupling heavy metal chelators to metal nanomagnets for rapid removal of cadmium, lead and copper from contaminated water

Chem Commun (Camb). 2009 Aug 28:(32):4862-4. doi: 10.1039/b909447d. Epub 2009 Jul 3.

Abstract

Attachment of EDTA-like chelators to carbon coated metal nanomagnets results in a magnetic reagent for the rapid removal of heavy metals from solutions or contaminated water by three orders of magnitude to concentrations as low as microg L(-1).
