Abstract
A new method to determine the degree of deacetylation (DD) of α-chitin and chitosan in the range of 17–94% DD using X-ray powder diffraction (XRD) is proposed. The results were calibrated using 1H 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.
