摘要：

Green chemistry approach has become the eco-friendliest and effective technique by using Ficus Benjamina for preparing bimetallic nanoscale zerovalent Fe/Cu particles and removal of phosphates from the aqueous solutions. Scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FTIR), and dispersive X-ray spectroscopy (EDAX) were used for characterisation. The removal adequacy of phosphates (5 mg L-1) reached to 73% under the condition of 0.3 g L-1, 30 min, and pH 4. The adsorption results are more appropriate by the Langmuir model [R2 = 0.998], with qmax = 17.42 mg g-1. The results of adsorption kinetics indicate that, phosphates uptake on Ficus-nZVFeCu is following the pseudo-second order model. Overall, Benjamina nZVFe/Cu is a committed green substance to remove phosphates. Operating parameters effect was investigated using a SPSS-linear regression analysis and found that more than 97% of the variables have an effect on the removal process. © 2021 Inderscience Enterprises Ltd.
