Abstract
Ferrite nanoparticles (NPS) of the structure CuNiFe2O4 were synthesized, and the auto combustion process was done using sol-gel. Several methods and nanomaterials have been identified using approaches such as Fourier- Transform Infrared Spectroscopy (FT-IR), X-Ray diffraction (XRD), and Filled Emission Scanning Electron Microscopy (FE-SEM). Measurements were made on the impact of temperature, pH, and contraction on the uptake behavior of CR dye. The ideal duration of interaction to achieve balance is 240 min, and the pH levels fall between 3 and 11. When compared to the Freundlich model, the desorption data demonstrated a good connection with the Lengmuir model. The thermodynamic parameters showed that ∆H was an exothermic reaction, ∆G was a spontaneous process, and ∆S had a negative value, indicating that the process was less disorderly and unpredictable.
