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 calibr...
An automatic system for the potentiometric determination of boron in ceramic frits was developed. The system includes a personal computer for instrumental control, data acquisition and processing, which allows up to 13 samples to be analysed sequentially with no human intervention.The system performance was tested on the titration of standard solutions, which it carried out with low errors and ...
