## Abstract Firstโderivative UV spectrophotometry is shown to be a reliable method for the determination of the degree of __Nโ__acetylation of chitosan samples. A mathematical expression is derived that allows to determine the DA directly from the mass concentration of a chitosan solution and the f

## Abstract A simple and rapid method for determining the degree of __N__โacetylation (__DA__) of chitosan by ultraviolet spectrophotometry using double beam equipment is proposed. DโGlucosamine (GlcN) hydrochloride and __N__โacetylglucosamine (GlcNAc) were used as model substances, and chitosan so
