Abstract The development of scientific approaches, for preparation of nano materials for the effective adsorption of mercury from natural gas condensate and wastewater using nano synthetic adsorbents is the focus of this study. This study investigated the removal efficiency of mercury species; HgCl2 and CH3HgCl from aqueous and oily phases respectively by mesoporous alumina. γ-Alumina substrates of high surface area (364-378 m2/g) were synthesized using aluminum hydroxide as starting material and CTAB as template by assistance of microwave irradiation at different (microwave watts, microwave times) and at different molar ratio concentrations between (aluminum hydroxide : CTAB and cosurfactant : aluminum hydroxide : CTAB). The activities of γ-alumina towards removing of different mercury species; HgCl2 and CH3HgCl from aqueous and oily phases respectively were investigated, before and after loading with different percentages of ZnO, ZnS, CuO and CuS ( 2.5, 5.0, 10.0 and 15.0 wt %) prepared by impregnation method. Zinc and copper MOF materials were prepared by using conventional heat and microwave irradiation processes. Evaluation of the adsorption capacity of the prepared material to adsorb the mercury species were carried out under different adsorption conditions. All materials were characterized by various techniques, such as Thermal Gravimetric Analysis (TGA), Nitrogen adsorption measurements (BET), X-ray diffraction (XRD), Fourier Transform Infrared (FT-IR) Spectrometry, High Resolution Transmission Electron Microscopy (HRTEM) and Scanning Electron Microscopy (SEM). BET results indicated that the surface area and pore volume of γ -Al2O3 increase with increase in microwave operation times and microwave operation watts but surface area and pore volume of γ -Al2O3 decrease with increase in molar ratio concentration Al(OH)3/CTAB and in concentration of cosurfactant. |
