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 a novel nanocomposite; Poly(acrylamide-co-Itaconic acid/TiO2) (P(AAM-co-IA/TiO2)) for Ce(III) sorption from monazite leachate. P(AAM-co-IA/TiO2) nanocomposite 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 mgg-1 at 298 K. The sorption reaction follows a pseudo−2nd - order mechanism. The process is spontaneous and endothermic.
