Abstract Green synthesis of zero-valent copper nanoparticles successfully performed using Ficus benjamina leaves. The novel adsorbent nano-zero-valent (FB-nZVCu) characterized by utilizing scanning electron microscopy (SEM) and Fourier transforms infrared spectroscopy (FT-IR). size these typically ranges from 16 to 18 nm. This investigated for removal D-blue 60 textile wastewater. impact differ...
