Abstract

AbstractThe sorption of Ag(I) ions on sorbents containing ethylenediamine (en) and iminodiacetate (ida) groups was investigated. The basic backbone consisted on macroporous glass coatd on its inner surface with poly(glycidylmethacrylate) (glass‐GMA), copolymer glycidylmethacrylate‐ethylenedimethacrylate (GMA‐EDMA), and GMA‐EDMA encapsulated in poly(‐2‐hydroxyethylmethacrylate). The rate of sorption of Cu(II) in sorbents modified with en decreased in the same order. For the sorption of Ag(II), a sorbent was synthesized by a reaction of GMA‐EDMA with 3‐aminopyridine, and the reaction with the ion was carried out in an oxidizing solution. The types of complexes formed in the sorption were determined spectroscopically in all cases.
