Gamma Irradiation-Induced Preparation of Polyacrylonitrile Acrylamide Nano-silica for Removal of Some Hazardous Metals

Gamma-irradiation initiated polymerization was utilized to prepare polyacrylonitrile acrylamide nano-silica (P(AN-AM)-NS). Various analytical tools like XRD, FT-IR, SEM, TEM, and DTA TGA were used estimate the morphology, functional groups, structure of P(AN-AM)-NS nanocomposite. The ability nanocomposite remove Cs(I), Pb(II), Cd(II), Sr(II), Cu(II) ions from multi-component system evaluated by batch techniques considering influence (shaking time, pH, reaction temperatures), capacity. At optimum distribution coefficients have selectivity order; Pb2+ > Cs+ Cu2+ Cd2+ Sr2+. kinetic data obey pseudo-second-order models. capacity reduced increasing heating temperatures solid powder. thermodynamic parameters showed an endothermic spontaneous. investigation proved that is a suitable organic–inorganic sorbent for sorption studied liquid solutions could be considered as potential material purification effluent polluted with these ions.
