Xanthan gum-graft-Acrylamide (XG-g-AM) was synthesized by ,60,Co γ-rays radiation. The effects of the different reaction conditions on the grafting degree and the grafting efficiency were explored. The structures of the grafted copolymers were characterized by means of Element Analysis (EA), Fourier-Transform Infrared Spectroscopy (FT-IR), X-Ray Diffraction (XRD), Thermal Gravimetric Analysis (TGA) respectively. The experiment results show that the optimized grafting reaction parameters, XG concentration of 10 g/L, AM and XG Mass ratio of 3:1, the total absorption dose of 6.0 kGy can make the grafting degree up to 128.5 % and the grafting efficiency to 80.4 %. And the flocculation performance of XG-g-AM has been also confirmed.
