The removal of copper {Cu(II)} and zinc {Zn(II)} ions from aqueous solution has been investigated using ground ficus
religiosa leaves (GFRL). The characterization of GFRL was performed using CHNS analyzer, X-ray diffraction (XRD) and
scanning electron microscope (SEM). The effect of contact time and initial concentration was observed at 33±1°C. The
biosorption of Cu(II) and Zn(II) on GFRL showed fast kinetic behavior with an equilibrium time ~ 60 minutes. The pseudo
second order kinetics described the kinetic behavior. The optimum GFRL dose was 10 g/L in case of both metals. The effect
of initial metal concentration showed the performance of GFRL under various mass transfer driving forces and was well
described by Langmuir Model with qmax: 28.02 mg/g for Cu(II) and 24.90 mg/g for Zn(II).
