Study on γ-Ray Irradiation Degradation of Chitosan
Abstract:
Chitosan was degraded by 60Co V-ray irradiation. The degradation kinetics, effect of irradiation on the degree of deacetylation(DE) of chitosan and the main chain scission mechanism have been studied. The results showed that the irradiation degradation of chitosan obeys the rule of random degradation. On irradiaton, DE was slightly raised and some of the C1-O-C4 bonds broke. Terminal groups with structure of W-lactone appeared produced during degradation.
