Ultrasound Mediated Modification and Characterization of Chitosan

摘要

Chemical modification of chitosan under sono-chemical conditions is carried out using citric acid as the crosslinking agent. The resultant cross-linked products are characterized by scanning electron microscopy, Fourier transform infrared spectroscopy and differential scanning calorimetric. It has been observed that the morphology and thermal stability of the cross-linked modified chitosan synthesized was dependent on the reaction temperature at which modification was done.
