Simple method on determination of deacetyllation degree for chitosan
Y Rohyami, NA Sari - AIP Conference Proceedings, 2021 - pubs.aip.org
The simple method of comparative study has been carried out for the determination of DDA
chitosan by infrared spectrometry and titrimetric. Determination of DDA by infrared
spectrometry has the data quantification technique with 4 different equations This study aims
to determine the significance of the DDA value with these equations. Including the titration
method, there are 4 techniques to determine the endpoint that has been reported in the
previous studies. The endpoint is indicated by phenolphthalein, methyl orange, and Conway …
