In the first research, the metal-organic-framework (MOF) MIL-47 was synthesized by the microwave method to remove dibenzothiophene. MOF structure was characterized by scanning electron microscopy, X-ray diffraction model, infrared spectroscopy, thermal gravimetric analysis, Nitrogen adsorption/desorption isotherms. DBT analyzed with a GC. Centeral Composite Design (CCD) was applied to optimize the adsorption process. Optimum points obtained with Design Expert software at 10 mg of absorbent, 800 mg/L of dibenzothiphene concentration and time 4H. The maximum adsorption capacity (Qo) was calculated based on the Langmuir adsorption isotherm Is equal to 1000 mg/g, Which indicates the high absorption capacity of the MIL-47.
In the Second research, the metal-organic-framework (MOF) MOF-5 was modified by CuCl2 at ambient temperature and pressure to remove congo red. MOF structure was characterized by scanning electron microscopy, X-ray diffraction model, infrared spectroscopy, thermal gravimetric analysis, Nitrogen adsorption/desorption isotherms.congo red analyzed with a UV-VIS . Centeral Composite Design (CCD) was applied to optimize the adsorption process. Optimum points obtained with Design Expert software at 10 mg of absorbent, 40 mg/L of congo red concentration, pH= 2 and time 2min. The maximum adsorption capacity (Qo) was calculated based on the Langmuir adsorption isotherm Is equal to 357/47 mg/g.
