Poly (acrylic acid-dimethylaminoethylmethacylate) resin was prepared by copolymerization technique. Gamma irradiation as initiator was used for the polymerization process. Obtained polymeric resin is an amphoteric ion exchange resin in which a quaternary ammonium group and a carboxyl group are incorporated on a cross-linked polymer frame. The physicochemical properties of obtained polymeric resin were determined using inductively coupled plasma (ICP), Fourier transform infrared spectroscopy (FTIR), TGA-DTA, and scanning electron microscope (SEM). Ion-exchange capacity (IEC), thermal stability, distribution behavior, etc. were also carried out to understand the adsorption behavior of the material. The equilibrium data were analyzed by the Langmuir and Freundlich isotherm models. The kinetic models’ data with zinc ions were studied.
