chelation
Ion capture process
Chelation is a chemical process in which a molecule binds tightly to a metal ion, gripping it from multiple points like a claw.
The word comes from the Greek for claw.
In medicine, chelation therapy uses compounds that bind to toxic metals like lead or mercury, allowing the body to excrete them: The child underwent chelation therapy for lead poisoning.
The process also has industrial applications in water treatment and food preservation.
