Chelating resin is a type of specialized polymer material that is used to selectively bind metal ions from solutions. These resins contain functional groups that can form stable complexes with metal ions, effectively “cheating” or sequestering them from a mixture. The term "chelating" comes from the Greek word "chēlē," meaning claw, which describes how these resins grab onto and hold the metal ions.
