Abstract:
Dyes are present in high amount in the effluent of many industries. The effectiveness of adsorption for dye removal from waste water has made at an ultimate alternative to other expensive treatment methods. The present work was aimed to prepare magnetic iron oxides nanoparticles Fe3O4 impregnated on apple seeds Testa powder for removal of cationic and anionic dyes from aqueous media. The method used for the synthesis of (ASTP-Fe3O4) was co-precipitation method. Synthesis of iron oxides nano particles Fe3O4 via this method is simple and easy approach. FeSO4 and FeCl3 were dissolved in distilled water with vigorous stirring. The solution was kept at 80°C. By adding ammonia formation of black precipitate MNPs occurred. ASTP was added to MNPs solution and then stirred for 24 hours at 80°C. The resultant (ASTP- Fe3O4) was filtered and dried in oven at 80°C. (ASTP- Fe3O4) will be characterized by Energy Dispersive x-ray (EDX), Scanning Electron Microscope (SEM), Fourier Transformation Infrared Spectroscopy (FTIR) and X-ray Diffraction (XRD) for surface area elemental composition, surface morphology, functional groups and crystallinity. The effect of different parameters such as adsorbent dosage, initial dye concentration, PH, and contact time were studied. The data obtained could be well defined by both the Langmuir and Freundlich adsorption isotherm models. The result indicated that electrostatic interaction was the main mechanism for the adsorption of these anionic dye (Alizarine Red S) and cationic dye (methyl violet).
