Abstract:Metal organic framework material,UiO-66 and UiO-66/carbon composites are synthesized by solvothermal method.The as-prepared samples are characterized by the powder X-ray diffraction,scanning electron microscopy and specific surface area.The results show that the crystal structure of the samples can be well matched with the standard data and the addition of carbon spheres can not change the crystal structure of UiO-6.The adsorption performance of the as-prepared material samples are tested by using methylene blue solution and methyl orange as the simulate dye wastewater.The results show that the adsorption performance of UiO-66 for MB can be greatly improved by adding carbon spheres.The adsorption capacity increased from 30 mg/g to 67 mg/g.Moreover,UiO-66 show remarkable adsorption performance for MO and the adsorption capacity can reach 226 mg/g.The adsorption behavior can be described by Pseudo-second-order kinetic model.
