Abstract:
In this study, a magnetic nanocomposite of metal-organic framework (NiFe2O4@SiO2@HKUST-1) with the weight ratio of nickel ferrite to silica matrix (10:90) was synthesized and characterized via the in-situ self-assemble method. Phase formation, type of formed bonds, morphology, crystal size, magnetic property and special surface area size werre characterized and investigated by X-Ray diffraction analysis (XRD), scanning electron microscopy (SEM) analysis, vibrating-sample magnetometer analysis (VSM) and Brunauer–Emmett–Teller analysis (BET). Finally, the removal of methylene blue cationic dye and the effect of pH on the removal rate were investigated. According to the obtained results in acidic environments, contact time of 60 minutes and 0.1 g of the synthesized magnetic nanocomposite of metal-organic framework, the highest adsorption capacity of the methylene blue cationic dye was observed. Experimental data were well-fitted with the Longmuir absorption isotherm. The kinetic studies showed that the process of adsorption of methylene blue dye at different pHs, was best described by a pseudo-second-order model.
