Abstract
This study was performed to achieve two important scientifically challenging goals, environmental remediation of toxic heavy metals and utilization of agricultural lignocellulosic wastes.
In this work, a series of mesoporous magnetic carbon (MMC) adsorbents were synthesized employing date palm (Phoenix dactylifera L.) stones as the carbon source and ferric nitrate as the iron source. The carbothermic reduction at different temperatures in nitrogen atmosphere was used as the synthesis method and the mechanism was discussed.
The precursor and synthesized adsorbents were characterized by thermal analyses, X-ray diffraction (XRD), elemental analysis, Field Emission Scanning Electron Microscopy (FESEM), and Nitrogen adsorption-desorption studies. The presence of zero valent iron nanoparticles and other iron oxides as products of the carbothermal reduction was confirmed.
The performance was evaluated in the removal process of toxic Cr(VI) in aqueous medium and the optimum conditions of the process were reported. The results were better fitted with pseudo second order kinetics and followed Freundlich model isotherm. The maximum adsorption capacity was found to be 265.25 mg/g for the mesoporous adsorbent carbonized at 700°C suggesting its application as efficient low-cost, and easily separable adsorbent for toxic Cr(VI) removal process.
