Abstract
Cellulose hydroxyapatite (Cel-HAp) nanometrics were prepared by microwave-assisted method in order to improve structural and morphological characteristics. The preparation of nanometric Cel-Hap was performed using different grades of cellulose (pharmaceutical aid and analytical reagent), CaCl2.4H2O and NaH2PO4.2H2O precursors. The mixture was heated in a microwave oven at low temperatures (70°C and 90°C) for five minutes .This method is applied in order to reduce synthesis time as well as to obtain materials more efficient to remove pollutant ions. The solids were characterized by Electronic Spectroscopy (DRUV), X-rays diffraction, Vibrational Spectroscopy (FTIR, Raman) and SEM. FTIR and Raman spectra show the characteristic bands of carbonated hydroxyapatite and cellulose. X-rays diffraction shows the typical diffraction peaks of HAp and Cellulose. SEM shows morphological differences between obtained solids: spicular (CelA-HAp, analytical reagent) and stacked layers (CelF-HAp, pharmaceutical aid) respectively. From the SEM studies and applying Scherrer's formula the materials were found to be nanometrics
