Characterization and Analyzation of Chitosan from <i>Anadara granosa</i> Shell

Abstract

This research work aims at characterize and analysis the physical and chemical properties of chitosan which derived from the Anadara granosa Shell. The physical and chemical properties have been also discussed in detail with X-Ray Diffraction (XRD), Fourier Transform Infrared (FTIR) Spectroscopy and Energy Dispersive X-Ray Fluorescence (EDXRF). The result showed that the XRD pattern indicated the Anadara granosa shell have crystalline structure of CaCO3 in Aragonite phase, while chitosan powder which extract from Anadara granosa shell has amorphous-crystalline structure. Another that, FTIR results confirmed the deeply formation of intermolecular bonding between the functional groups of the sample which the spectrum of FTIR indicate that the characteristic feature of Aragonite phase with the band of FTIR at ~1083 while the band at ~1653 were agree with chitosan polysaccharide. In addition, the EDXRF result were indicated that the concentrations of organic compounds in chitosan which extract from Anadara granosa shell have concentration is 33.581Wt% while the Anadara granosa shell have 0.033 Wt%. For Calcium (Ca) element the chitosan powder have concentration is 66.157 Wt% while the Anadara granosa shell have 99.850 Wt%.
