Abstract

• The purpose of this research work was to study the elemental cocentrationand mode of chemical group between the possible vibrational frequencies in parts of Aloe vera plant by using Energy Dispersive X-ray Fluoresence (EDXRF), Fourier Transform Infra-Red (FTIR) and Ultraviolet and Vissible (UV-vis) Spectroscopy techniques. Hydrogel films composed of polyvinyl alcohol(PVA) and Aloe vera(AV) gel were prepared and characterized by different ratio of PVA/AV hydrogel films 1:1, 1:2and 1:3 variations in the Aloe vera content. From the the results obtained that Aloe vera improves the water absorption rate of the films. and average equilibrium water content is 84.67%. The morphological characterization of the film by Scanning Electron Microscopy (SEM) analysis.
