Chelation is a type of bonding of ions and molecules to metal ions. It involves the formation or presence of two or more separate coordinate bonds between a polydentate (multiple bonded) ligand and a single central metal atom. These ligands are called chelants, chelators, chelating agents, or … See more The chelate effect is the greater affinity of chelating ligands for a metal ion than that of similar nonchelating (monodentate) ligands for the same metal. The thermodynamic principles underpinning the … See more Catalysis Homogeneous catalysts are often chelated complexes. A representative example is the use of See more Dechelation (or de-chelation) is a reverse process of the chelation in which the chelating agent is recovered by acidifying solution with a … See more • Chelation therapy – Medical procedure to remove heavy metals from the body • EDDS – chemical compound See more Numerous biomolecules exhibit the ability to dissolve certain metal cations.
