This study aimed to evaluate the removal of cadmium using a magnetic nano sorbent derived from Eucalyptus extract. The sorbent was characterized by X-ray diffraction analysis, field emission scanning electron microscopy, energy-dispersive X-ray spectroscopy, vibrating sample magnetometer, and Fourier-transform infrared spectroscopy. Factors affecting Cd uptake, including pH, initial Cd concentration, temperature, and contact time, were studied. Response surface methodology and an adaptive network-based fuzzy inference system were employed to predict the optimum conditions for cadmium adsorption. Various models were used to fit the kinetic experimental data, and thermodynamic variables were calculated.
