In the present investigation of copper ferrite, a CuFe2O4 nanocomposite adsorbent was synthesized using sol–gel method, and its relevance in adsorptive elimination toxic Congo red (CR) aqueous phase examined. A variety structural methods were used to analyze nanocomposite; as-synthesized had agglomerated clusters with porous, irregular, rough surface that could be seen FE-SEM, it also contained carbon (23.47%), oxygen (44.31%), (10.21%), iron (22.01%) elemental composition by weight. Experiments designed achieve most optimized system through utilization central composite design (CCD). The highest uptake CR dye at equilibrium occurred when initial pH value 5.5, adsorbate concentration 125 mg/L, dosage 3.5 g/L. Kinetic studies conducted, they showed adsorption process followed pseudo-second-order (PSO) model (regression coefficient, R2 = 0.9998), suggesting chemisorption mechanism, overall reaction rate governed both film pore diffusion molecules. which molecules taken up onto particle revealed interactions involving electrostatic forces, hydrogen bonding, filling. According isotherm studies, data exhibited strong agreement Langmuir (R2 0.9989), demonstrating maximum monolayer capacity (qmax) 64.72 mg/g 6 302 K. Considering obtained negative ΔG positive ΔHads ΔSads values across all tested temperatures thermodynamic investigations, confirmed characterized as endothermic, spontaneous, feasible, an increased level randomness. developed this study is anticipated find extensive application effluent treatment, owing excellent reusability remarkable capability effectively remove comparison other adsorbents.
