Abstract

The influence of different intensities of ultrasound on the molecular weight of CHITOSAN was investigated. Average molecular weight of ultrasonicated CHITOSAN was determined by measurements of intrinsic VISCOSITY of samples. Intrinsic VISCOSITY of samples decreased exponentially with increasing sonication time. The Schmidt polymer degradation model was used to analyze the molecular weight decay as a function of sonication time as well as rate constant determination. In addition, the structure of the degraded CHITOSAN was characterized by FT-IR spectral analysis. There was no significant change of the total degree of deacetylation (DD) of degraded CHITOSAN compared with the initial CHITOSAN.
