To purge wastewater of methylene blue dye, we used a nickel ferrite nanocomposite. The FTIR, XRD, and SEM analyses revealed the nanocomposite's nickel ferrite composition. To determine the efficacy of the nickel ferrite nanocomposite in removing methylene blue dye, we performed adsorption experiments. We adjusted the physicochemical factors such as temperature, pH, beginning concentration, carbon dosage, and length of contact. A contact period of 60 minutes was determined to be optimal for the adsorption process. Utilizing the following models: Elovich, intraparticle diffusion, pseudo-second order, and pseudo-first order, we examined the collected experimental data. In order to analyze the equilibrium data, we have used Freundlich and Langmuir isotherms. The adsorption mechanism of methylene blue dye is well-described by the Freundlich isotherm model. Research into adsorption kinetics confirmed the superiority of the pseudo-second-order kinetic model.
