Determination of the degree of deacetylation of chitin and chitosan by X-ray powder diffraction.
Carbohydr Res. 2005 Aug 15; 340(11):1914-7.CR

Abstract

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.
