Determination of the degree of deacetylation of chitin and chitosan by X-ray powder diffraction.

چکیده
A new method to determine the degree of deacetylation (DD) of alpha-chitin and chitosan in the range of 17-94% DD using X-ray powder diffraction (XRD) is proposed. The results were calibrated using (1)H NMR spectroscopy for chitosan and FTIR for chitin, in comparison with the potentiometric titration method. The results showed a good linear correlation between the CrI020 from XRD and the calibrated DD value. This method is found to be simple, rapid and nondestructive to the sample.

Background and purpose: Chitin is one of the main components of crustaceans’ exoskeleton. Chitosan is produced by deacetylation of chitin. Molecular weight and degree of deacetylation play important roles in biological activity of chitin, chitosan, and their derivatives. So far, various derivatives of chitin and chitosan are obtained. The purpose of this study was to prepare derivatives o...

This study presents the first ever data of extracting chitin from the Chiton shell, which then converted to the soluble chitosan by soaking in the 45% NaOH solution. The obtained chitin and chitosan were characterized by the seven different methods. Antioxidant activity of the extracted chitosan was also evaluated using the two methods. The shell content was divided into calcium carbonate (90.5...
