The presence of the amide III band (1322.9 cm-1) and the C-CH3 deformation vibration absorption peak (1322.9 cm-1) indicated that a certain amount of acetyl groups were present in the chitosan molecule [20].The peaks at 1151.3cm-1 and 896.8cm-1 were characteristic absorption peaks of β-(1→4) glycosidic bonds [21].
