Abstract

In this study, the co-precipitation method was used to synthesize Fe-doped ZnO/Montmorillonite (Fe:ZnO/MMT) nanocomposites with various amounts of MMT. Thermogravimetric analysis, X-ray diffraction, and Brunauer-Emmett-Teller surface area analysis measurements were used to characterize the samples. The adsorption of methylene blue was conducted using the nanocomposites. The effect of MMT amounts, pH values, and initial concentration of the dye were investigated. The adsorption mechanism was better fitted with pseudo-second-order kinetic model than pseudo-first-order kinetic model. The adsorption isotherms of the nanocomposites were better fitted with Freundlich isotherm model than Langmuir isotherm models.
