The mechanism of the interaction of iron(III) with polymeric ligands of vibrous structure, viz., polyvinyl alcohol (PVA), a copolymer of polyvinyl alcohol and polyacrylonitrile (PVA-PAN), and a thioamidated copolymer of polyvinyl alcohol and polyacrylonitrile (PVA-PAN-T), has been established by Moessbauer spectroscopy. It has been found that Fe(III) is partially or completely reduced to Fe(II) during sorption and that both forms of iron coordinate the oxygen-containing functional groups of the polymers.
