Study on Chemical Compositions and Crystallinity Changes of Bamboo Treated with γ Rays
The structures and qualities of main chemical compositions in cell wall of bamboo treated with γ rays were tested by nuclear magnetic resonance spectrometer (NMR) and X-ray Diffraction (XRD). The result indicated that the bamboo crystallinity increased at the beginning of irradiation process, while the crystallinity reduced when the irradiation dose was raised to about 100 kGy. During the whole irradiation process, hemicellulose degraded, and with the irradiation doses increased the non-phenolic lignin changed to the phenolic.
