Abstract
Dyes pollution is a major problem in the water, especially since the main factor is textile factories. The treatments for this problem through nanomaterials have taken a broad scope and many studies. In this study, trinary Novel metals oxide [CuNiFe2O5] nanocomposite is successfully synthesized by Uv-irradiation presses with a maximum intensity wavelength at 365 nm. The nanocomposite was investigated by scanning and transmission electron microscopy measurements (SEM and TEM), and their crystal structure is obtained by the X-ray diffraction technique (XRD). The percentage of elements on the sample was determinate by an Energy-dispersive X-ray spectroscope (EDX) and X-ray mapping. The energy gap is equal to 2.48 eV calculated by photoluminescence spectroscopy (PL). Incorporating CuNiFe2O5 NPs enhanced the uptake of Cibacron brilliant red dye (CBR). A faster CBR adsorption onto CuNiFe2O5 nanocomposite at a contact time of 90 min. The Freundlich (R2 > 0.9684) and pseudo-second-order (R2 > 0.9724) models were most appropriate in the description of the adsorption process. A thermodynamic study was performed to calculate the ΔG, ΔH, and ΔS parameters of 1.415 kJ/mol, 7.63 J/mol K, and 20.8 J/mol. Finally, The novel synthesized nanocomposite is a good adsorbate surface for Cibacron brilliant red dye.
