✦ Synopsis

A series of chelating resin containing N, O, S atoms were synthesized by incorporating ethanolamine, 2-mercaptoethylamine (MEA), iminodiacetic acid (IDA), 8-quinolinol and anthranilic acid into chloromethylated polystyrene-divinyl benzene (CPS), and then they were treated with FeCl 3

aqueous solution to form the metal complex on the surface. Conversion of functional groups of the CPS resin was confirmed by IR spectra and elemental analysis. IR and ESR were used to investigated the coordination behavior of these resins. The metal content of these metal complexes was estimated by atomic absorption spectroscopy. The thermal stability of them was seen by TGA. By catalyzing the acetalization of carbonyl compounds they were found to be effective and could be reused with no substantial loss of activity for up to 10 cycles.
