Record Type: concept
chelating agent (<materials by function>, materials (substances), Materials (hierarchy name))

 

Note: Organic chemical compounds capable of forming coordinate bonds with metals. Chelating agents are used to sequester or remove residual trace metal ions from materials to which they have attached. In a conservation context, uses of chelants include stabilizing of paper containing iron-gall ink, removal of iron residue from platinum prints; treatment of excavated copper objects.
