Novel Terpolymer Resin: Synthesis, Characterization and Ion-Exchange Studies of Terpolymer and its Composite

A novel terpolymer containing biuret, 4,4'-oxydianiline and formaldehyde (BODF) was synthesized by condensation polymerization technique of biuret and 4,4'-oxydianiline with formaldehyde at different mole ratios (1:1:2) in dimethylformamide medium. The newly synthesized terpolymer was converted into its composite with chitosan. The terpolymer and its composite were characterized and confirmed by elemental analysis, FTIR, 1H & 13C NMR and UV-vis studies. The surface morphology of synthesized terpolymer resin with the incorporation of chitosan was examined by scanning electron microscopy (SEM). The chelation ion-exchange studies of synthesized terpolymer and its composite for the various metal ions were also carried out by batch equilibrium method under the estimation of metal ion uptake at different electrolytes and pH.
