Study on the synergetic degradation of chitosan with ultraviolet light and hydrogen peroxide.

Shi-Ming Wang1, Qun-Zeng Huang, Qiong-Sheng Wang.   

Abstract

Chitosan was effectively degraded by hydrogen peroxide under irradiation with ultraviolet light. The existence of a synergetic effect on the degradation was demonstrated by means of viscometry. In addition, the optimal conditions of degradation were determined on the basis of orthogonal tests. The structure of the degraded product was characterized by Fourier-transform infrared spectra (FTIR) analysis and diffuse reflectance spectra (DRS) analysis. The mechanism of the degradation of chitosan was correlated with cleavage of the glycosidic bond.
