chelate
Chemically grab metal
Chelate describes a chemical compound in which a central metal atom is bonded to a surrounding molecule at multiple points, forming a ring-like structure that grips the metal like a claw.
The verb means to form such a bond or to use chelating agents medically to remove toxic metals from the body: Chelation therapy can treat lead poisoning.
In chemistry, chelating agents are used to sequester unwanted metal ions.
