Cadmium pollution is known to cause severe public health problems. This study is intended to examine the effect of an activated Firmiana Simplex Leaf (FSL) on the removal of Cd(II) from aqueous solution. Results showed that the active Firmiana Simplex Leaf could efficiently remove Cd(II) from wastewater due to the preservation of beneficial groups (amine, carboxyl, and phosphate) at a temperature of 250 degrees C. The adsorbent component, dosage, concentration of the initial solute, and the pH of the solution were all found to have significant effects on Cd(II) adsorption. The kinetic constants were predicted by pseudo-first-order kinetics, and the thermodynamic analysis revealed the endothermic and spontaneous nature of the adsorption. FT-IR and XRD analyses confirmed the strong adsorption between beneficial groups and cadmium ions, and the adsorption capacity was calculated to be 117.786 mg g(-1) according to the Langmuir isotherm.
