Synthesis and Characterization of Magnetic Nickel Ferrite-Modified Montmorillonite Nanocomposite For Cu (II) and Zn (II) Ions Removal From Wastewater

For the adsorption of copper (II) and zinc ions from polluted water, an efficient inexpensive nanoadsorbent; nickel ferrite-modified montmorillonite nanocomposite was synthesized by co-precipitation mechano-chemically modified with salts iron. The natural MMT, (NiFe2O4-Mod MMT) nanoadsorbent were characterized several techniques including Fourier transform infrared spectroscopy, X-ray diffraction, transmission electron microscopy, energy-dispersive X-ray, surface area analysis, saturation magnetization, zeta potential. Batch studies carried out on effect various parameters contact time, dosage, solution pH, metal ion initial concentration, temperature process to optimize its conditions. equilibrium state reached after 60 min 90 reaction for Cu Zn ions, respectively. optimum conditions 0.1 g adsorbent dose, pH 5, 13 mg/L 298 K 6, 6 adsorption. Among designed kinetic models, pseudo-second-order model Langmuir isotherm have controlled both ions. Furthermore, mechanism reproducibility investigated. maximum efficiency 99.23% 91.67%
