ABSTRACT

Effect of ⁶⁰Co-γ irradiation treatment on cellulose structure originating from Phragmites communis trim (PCT) was investigated on the basis of irradiation doses of 0 to 2000 kGy at a dose rate of 2 kGy h^-1. Scanning electron micrograph images showed that surface morphologies of PCT cellulose could become fragmented after being treated with ⁶⁰Co-γ irradiation. Based on X-ray diffraction profiles, crystallinity and amorphous region of microcrystalline cellulose treated by irradiation were obviously changed. Fourier transform IR spectroscopy data indicated that a new characteristic peak corresponding to carbonyl (1734 cm ^-1) appeared after PCT cellulose was treated with ⁶⁰Co-γ irradiation, which suggested that PCT cellulose was degraded after irradiation treatment.
