In this study, Acrylamide (AAM), Itaconic acid (IA) and nano TiO2 were copolymerized using gamma irradiation with 60Co γ-rays at a dose of 25 KGy to form poly (acrylamide-co-Itaconic acid/TiO2) (P(AAM-co-IA/TiO2)). Different compositions of P(AAM-co-IA/TiO2) nanocomposites are prepared and examined for Ce(III) sorption. The optimum composition is C6P(AAM-co-IA/TiO2); 61.54 AAM: 30.77 IA: 2.56 TiO2: 5.13 DAM with sorption efficiency at 298 K, pH 6 after 60 min is 80% for initial Ce(III) concentration 200 mgL–1. C6P(AAM-co-IA/TiO2) is characterized by different physicochemical techniques. The optimum pH for the sorption process at 298 K is 6 and the equilibrium attained after 60 min. Different kinetics and isothermal models is applied. The monolayer adsorption capacity is 76.04 mg g–1 at 298 K. The sorption reaction follows a pseudo - 2nd - order kinetic mechanism. The change of Gibbs free energy is – 4.78 kJ/mol at 298 K and change in enthalpy is 60.874 kJ/mole, i.e., the process is spontaneous and endothermic.
