摘要: Abstract In the present paper, depolymerization of chitosan was carried out by ultraviolet-irradiated oxygen treatment. Influence reaction conditions on investigated. The chemical structure depolymerized characterized FT-IR and 13 C NMR spectra. spectra suggested that there no obvious modification chitosan. X-ray diffraction analysis showed crystalline can be destroyed oxygen. use treatment a convenient, timesaving, cost-efficient method for replacing expensive time-consuming enzymatic or methods are currently used to depolymerize
