Study on phenol adsorption onto Fe-MIL101 in aqueous solution
Abstract
In the present work, Fe-MIL101 formed by hydrothermal synthesis with ligand of H2BDC was characterized by physico-chemical mehods including X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDX), scanning electron microscopy (SEM) and N2 adsorption-desorption isotherm (BET). The results showed that the obtained material exhibited rather good crystallization, uniform crystals’ size and high BET surface area (736 m2.g-1). Phenol adsorption ability in aqueous solution onto Fe-MIL101 material was investigated. With adsorbent’s dosage of 4 g/L-1 and at suitable pH of 6-8, 55 % of phenol was removed from aqueous solution containing 20 mg phenol.L-1. Adsorption isotherm study confirmed Langmuir model well described the experimental data and maximum adsorption capacity was about 4,6 mg.g-1.
