Removal Performance Assessment of Dyes in Solution Using Mesoporous MCM-41 Prepared from Iraqi Rice Husk
AbstractIn this study, mesoporous silica MCM-41 material was synthesized using Iraqi rice husk for the first time, as silica precursor and Cetyltrimethylammonium bromide (CTAB) as a template. MCM-41 was characterized by means of X-ray diffraction (XRD), scanning electron microscopy (SEM), BET surface area, Fourier transform infrared (FTIR) spectroscopy and Thermal Gravimetric Analysis (TGA). Then the ability of MCM-41 as adsorbents were tested to treat dyes as one of the organic pollutants from synthetic wastewater . The adsorption behavior of Gentian violet(GV), Methylene blue(MB) and Congo red(CR) dyes from synthetic wastewater onto mesoporous MCM-41 was tested. Batch adsorption was employed to determine the effects of pH (2-11), adsorbent dose (0.05-1g), contact time (0–200 min), initial concentration (25-300 mg/L) and temperature (293,313,333ͦ K). It was found that MCM-41 has higher potential for adsorption of basic dyes (GV, MB) and lesser for acidic dye (CR) from aqueous solution in batch system .Adsorption isotherms were fitted with the Langmuir, Freundlich, and Temkin models. It was found that the Langmuir adsorption isotherm model for GV and CR had the best fit with; on the other hand, the Freundlich adsorption isotherm model had the best fit for MB.
