Abstract: A UV spectrophotometric method for the determination of the deacetylation degree of chitin is described based on the stability of chitosan in 0.001mol/L hydrochloric acid. The method is rapid, simple and the pretreatment of the samples is not necessary.

Key words: chitin, chitosan, deacetylation degree, UV spectrometry
