Abstract: Bimetallic zero-valent iron/copper NPs were successfully prepared by green synthesis approach using Ficus Benjamina leaves extract (FB-nZVFe/ Cu). Scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FT-IR), and dispersive X-ray spectroscopy (EDAX) indicating the synthesising of bimetallic Ficus-ZVFe/Cu nanoparticles. The removal efficiency of diclofenac sodium (50 mg L-1) reached 95% under the condition [0.5 g L-1, 45 min, and pH4]. The adsorption data are more appropriate by the Langmuir model [R2 = 0.9983] with qmax = 155.6 mg g-1. Results of adsorption kinetics indicate that DFS uptake on FB-Fe/Cu nanoparticles is following the pseudo-second-order. Overall, FB-Fe/Cu nanoparticles are a committed green substance to remove DFS. Operating parameters effect was investigated using linear regression analysis SPSS, and they were found to account for more than 98% of the variables that affect on the removal process.
