چکیده انگلیسی
Amino-functionalized mesoporous materials based different mesoporous silica were prepared for the recovery of Mo(VI) from Re(VII)-containing solutions. The adsorption materials were characterized by SEM, HRTEM, TGA, XRD, N2 adsorption-desorption isotherms and Elemental analysis. The optimum type (SS5-1h-5.5@95) of mesoporous silica was determined by anchoring of mesoporous silica substrate with 3-aminopropyltriethoxysilane (APTES) via conventional methods and partitioned cooperative self-assembly process (PCSA process). Adsorption experimental data showed that the SS5-1h-5.5@95-APTES had a high affinity for Mo(VI) from Re(VII), and the maximum adsorption capacity was evaluated as 194.32 mg gâ 1 in case of pH 1. Moreover, adsorption behavior, adsorption isotherm, adsorption kinetics and thermodynamics of Mo(VI) on the SS5-1h-5.5@95-APTES were studied, and adsorption mechanism was confirmed by FT-IR, Raman spectra and XPS analysis. The excellent affinity and selectivity make the SS5-1h-5.5@95-APTES become a potential material for recovery Mo(VI) from Re(VII) solution.
