Abstract

The DEGREE OF DEACETYLATION (DD) of CHITOSAN plays a main role in its physical, chemical and biological properties. Hence, in this study, low-viscous, medium, and high (impure and improved) molecular weight CHITOSAN were used to determine DD, using a simple and exact method, The DDs of CHITOSAN were determined by the fourier transform INFRARED SPECTROSCOPY (Baseline-a and b) and linear POTENTIOMETRIC TITRATION. Thie concluded results were compared using Root-Mean-Square Deviation (sRMSD) whereby an agreement between the linear POTENTIOMETRIC TITRATION and fourier transform INFRARED SPECTROSCOPY (Baseline-a) were shown. In presented method, for purifying impurities and improving DD of the high molecular CHITOSAN, DD was noticeably increased from 60.1 to 92.7 %. The analysis of CHITOSAN's DD represented the raise of DD in the presence of the increase of viscosity and molecular weight of CHITOSAN.
