Abstract
Crosslinking and protonation of Chitosan meinbranes (prepared by solution
casting technique) with sulfuric acid and systematic study on its variation of
optical band gap, type of transition and the shape of the absorption edge for
different concentration (O.IM - ch-1, 0.5M - ch-5 and 0.9M ch-9) of
sulfuric acid through IJV-Visible Spectroscopy have been investigated, fhe
synthesized Chitosan membranes of 25 pm thickness were subjected to XRD
(X-Ray Diffraction) analysis to determine the structure. From the results it is
proved to be amorphous in nature exhibiting some crystalline peaks (20)
around 10'\ 1 5" and 20'\
