Chelation: Harnessing and Enhancing Heavy Metal …
“Chelation,” from “chelos” the Greek word for claw, involves the incorporation of a mineral ion or cation into a complex ring structure by an organic molecule, the chelating agent. Typically, electron-donor atoms on the chelating molecule include sulphur, nitrogen, and/or oxygen.
Chelating agents control metal ions by blocking the reactive sites of the metal ion and preventing them from entering into their normal (and in many cases undesirable) reactions.
Chelating Agent - an overview | ScienceDirect Topics
Chelating agents are chemical compounds whose structures permit the attachment of their two or more donor atoms (or sites) to the same metal ion simultaneously and produce one or more rings. These molecules are also called “chelates” or chelating groups, and the formation of rings is called “chelation.”
