Comparation Trace Element and Structural of Filler Materials in Chitosan Films

In present study, the structural and trace element were preliminary survey the potentiality to use as filler material for produced the biocomposite films. The first raw material is chitosan and the second raw material is chicken eggshell. Both raw material were investigated the structural and morphological with X-ray Diffraction (XRD) and Scaning Electron Microscope (SEM), respectively. While, Fourier transform infrared spectroscopy (FT-IR) the Energy Dispersive X-ray Fluorescence (EDXRF) were used to investigate functional group and trace element, respectively. The result show that, both material have crystalline structural. The chicken eggshell have calcite structure while the chitosan have amorphos-crystalline structure. The chemical composition in both material compose of P, Ca, Fe similarly but the concentration have been different.
