In this work, zeolitic imidazolate framework-67(ZIF-67) was synthesized by using microwave-assisted method. The obtained ZIF-67 was characterized by means of scanning electron microscope (SEM), X-ray diffraction (XRD), and thermal gravity analysis (TG). The microwave-assisted method enabled to fabricate ZIF-67 with high yield rate and high specific surface areas of 1935 m2/g in relatively short time as compared to hydrothermal and solvothermal approaches. The Langmuir and Freundlich isotherm models were utilized to determine the adsorption capacity of ZIF-67. It was found that the adsorption capacity of ZIF-67 for RDB could be as high as 123,5 mg/g.
