Green Synthesis of Nano-Zero-Valent Copper for the D-Blue 60 Textile Dye Removal from Aqueous Medium

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 different operating parameters, including pH, dose, stirring rate, time, initial dye concentration, had been tested, optimum conditions were selected gauge the performance adsorbent. maximum efficiency reached 87% under following proper conditions: dose 0.3 g L −1 , time 30 min, pH 8. Langmuir isotherm was found be most appropriate system adsorption process ( R 2 = 0.9994) q max 30.03 mg ). pseudo-second-order model defined adsorption. From data obtained fruitful discussion, it detected that FB-nZVCu green strongly recommended as a hopeful substance removing both synthetic actual waste samples. Highlights eco-friendly low-cost material are efficient nano-adsorptive agents wastewater conditions. PSO kinetics provided good fit data.
