The ion-exchange technique has been involved for the removal of heavy metal from different aqueous solution. The terpolymer resin was synthesized by condensation polymerization of o-toludine and 8-hydroxyquinoline with formaldehyde resin using dimetylformamide (DMF) as a reaction medium in 1:1:2 ratio at 130°C for 6 Hrs. The composite was prepared by terpolymer and activated charcoal. The structure of the prepared Terpolymer resin and composite were established by the elemental analysis and other spectral studies such as FTIR and NMR(1H&13C). The surface morphology of the adsorbents have been determined by SEM. The prepared adsorbents were subjected to removal of selective metal ions like Cu2+, Zn2+, Co2+, Pb2+ in different electrolyte concentrations, different pH ranges and different rates by Batch equilibrium method. The results revolved that, the terpolymer and its composite have good adsorbents. The adsorbents were an effective metal ion removal for Zn2+ than other metal ions. The metal ion capacity of the adsorbents also compared with other commercial resin.
