Abstract :

Production of chitosan from shrimp producted chitin with two acids and determination degree of acetylation by FT-IR spectroscopyAbstract:After cellulose, chitin found in nature in the shells of crustaceans, exoskeleton of insects, nematodes, and fungi cell wall in complex forms with other proteins and polysacharids. Chitosan produced by deacetylation of chitin and used in medico until agriculture. The chitin with different percentages of industrial acid was prepared from shrimp shells and functional properties of chitosan prepared from these samples by Fourier transform (FTIR) was studied. FTIR pattern almost matched samples with standard samples. The preparation of chitosan film and its IR spectrum showed that the degree of acetylation of chitosan obtained between 22-18 liable by Brugnerotto and coworker (2001) method. In view of shrimp abondance in northern and southern parts of the country, The commissioning a very precious product line is the possibile that economic growth and replacing it with chemicals incompatible with the environment in solving the environmental problems of human societies is the most effective.Keywords: Chitin, Chitosan, FTIR, Acetylation degree.
