Abstract
Chelating terpolymer resin was synthesized and characterized by elemental, physico-chemical, spectral, SEM, XRD, and GPC to elucidate the structure and properties of the terpolymer. Ion-exchange analysis involving evaluation of metal ion uptake in different electrolyte concentrations, pH, and time have been studied to assess the retention capacities of the terpolymer for the metal ions viz. Fe3+, Co2+, Ni2+, Cu2+, Zn2+, and Pb2+. The adsorption isotherm was evaluated using the Langmuir and Freundlich isotherms models and the results were found best fitting with each other. The resin can be successfully used in the field of recovery of metal ions from effluents and contaminated water.
