| Popis: | The present work aims to characterize two types of softwood waste “Cedar” and hardwood waste “Mahogany” collected from a local industry in the region of Fez/Morocco. These sawdusts are physically pre-treated and then characterized by X-Ray Fluorescence (XRF), X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy (SEM). X-ray fluorescence analysis allowed the determination of organic and inorganic contents (CaO, MgO, SiO2, Al2O3 ...) for each type of sawdust. X-ray diffraction revealed the presence of the crystalline phases of cellulose, with a higher crystallinity index for Cedar than in the case of Mahogany. The results obtained by infrared spectroscopy, are consistent with those obtained by DRX and FX. Scanning electron microscopy allows to analyze the morphology of these samples. This study clarified the similarities and differences in the chemical composition and morphological structure of these two sawdusts, paving the way for potential applications in the field of effluent treatment. |
