## Abstract Equilibrium isotherms have been studied for the adsorption of four dyestuffs, namely, Acid Blue 25, Acid Blue 158, Mordant Yellow 5, and Direct Red 84, onto chitin. Langmuir and Freundlich constants have been determined and the effects of chitin particle size and solution temperature ha
Free amino groups in @-chitin from squid pen were acetylated to obtain N-acetylated Pchitin. After careful control of degree of acetylation, thermal and mechanical properties of P-chitin and N-acetylated @-chitin were compared. The structural differences of P-chitin and N-acetylated 6-chitin were ch
