Titanium dioxide/polyethylene glycol (TiO2/PEG PNC)-nanocomposite was prepared using the wet chemical method. Physico-chemical characterization of TiO2/PEG PNC is studied by TEM, FTIR, XRD, DTA-TGA, particle size distribution, and pore size analysis. TiO2/PEG PNC used for sorption of 134Cs and 60Co radionuclides. The TiO2/PEG PNC sorption monolayer capacities towards 134Cs and 60Co radionuclides at pH 5 and 25 °C is numerically equal to 163.28 ± 10.98, and 330.16 ± 41.60 mg g−1, respectively. The kinetic of the sorption reaction is applicable with a pseudo-second-order model. The sorption reaction is favorable and endothermic.
