【Abstract】 Potential titration curve of deacetylation degree of chitosan was studied by Microsoft Excel software. The deacetylation degree can be calculated through the volume of sodium hydroxide used between two abrupt change. This method is accurate, reliable and with good repeatability. The RSD is less than 0.9%.更多还原
