“…Modified iron oxide nanoparticles have good potential for the wastewater treatment process as has been exemplified in the rapid green synthesis of magnetic nano-sorbents by using extracts such as Nelumbo nucifera stalks, Colocasia esculenta corms, and Piper betle leaves; they provide an efficient, facile, and environmentally friendly route for the modification of nanoparticles (Misra et al, 2018), and as illustrated, in the good adsorption efficiency for carbamazepine.…”

“…In contrast, since carbamazepine is neutral in the range of pH 3-10 (To et al 2017). At pH 3, low removal efficiency due to the presence of H + ions that occupy available vacant sites, which interfere with the FB-nZVFe/Cu particles (Misra et al 2018). At pH 9, the removal efficiency was very low, due to the repulsion, and occurs between OH − ions and negative charged surface of nanoscale particles, thus leading to steric hindrance and weak interaction (Misra et al 2018;Shan et al 2016), or may be the low availability of nanoparticles (Misra et al 2018).…”

Green synthesis of nanoparticles is an eco-friendly treatment technique. Bimetallic nano zero-valent Fe/Cu was successfully prepared by green synthesis by Ficus Benjamina leaves (FB-ZVI/Cu). The nanoscale FB-ZVI/Cu was characterized by scanning electron microscope, Fourier transform infrared spectroscopy, and dispersive X-ray spectroscopy. The characterization revealed that synthesis and presence of iron-copper nanoparticles and biomolecules which could help in capping the bimetallic nanoparticles. Subsequently, nanoscale zero-valent Fe/Cu particles were used to remove carbamazepine from the aqueous medium under varying experimental conditions, including pH, initial carbamazepine concentration, Fe/CuNPs dose, stirring rate, and contact time. The removal efficiency of carbamazepine reached 95% under the condition of dose 0.4 g L −1 , time 20 min, and pH 5. The results were analyzed according to the Freundlich and Langmuir adsorption isotherms. The adsorption data are more appropriate by the Langmuir adsorption model (R 2 = 0.998) with q max = 26.15 mg g −1. Overall, FB-nZVFe/Cu is a promising green substance to remove carbamazepine from aqueous solutions. The effect of different operating parameters was investigated using linear regression analysis, they were found to account for more than 97% of the variables affecting the removal process. Article Highlights • Bimetallic nZVFe/Cu was synthesized using the Ficus Benjamina leaves' extracts. • Nanoparticles were characterized by SEM, EDAX, and FTIR. • The green-synthesized FB-nZVFe/Cu nanoparticles can remove carbamazepine from aqueous solutions. • Removing mechanism based on adsorption and reduction is proposed. • A high removal percentage of carbamazepine was 95%. • Lower FB-nZVI/Cu PZC values.

“…At pH<pHpzc [pH 3], Low in the removal capacity due to the presence of an excess of H + ions that occupy available vacant adsorption sites, and the free e - neutralize the solution, and portion of nanoparticles dissolve in the medium (Mahmoud et al., 2018c). At pH> PZC [pH 9], because of the repulsion between OH - ions and negatively surface of FB-nZVFe/Cu is negative (Misra et al., 2018; Shan et al., 2016); and maybe the low availability of nanoparticles which precipitates in the solution (Mahmoud et al., 2018b), thus leading to low removal efficiency. Based on the above pHpzc is the optimal removal of Caffeine.…”

Green synthesis approach was successful used extract was successful in preparing bimetallic zero-valent Iron/Copper nanoparticles [FB-nZVFe/Cu]. Scanning Electron Microscope [SEM], Fourier Transform Infrared Spectroscopy [FTIR], and Dispersive X-ray Spectroscopy [EDX] showing the synthesizing of FB-nZVFe/Cu. The removal efficiency of Caffeine [5 mg L−1] reached 86% under the conditions [0.2 g L−1, 45 min, and pH 5]. The adsorption data are more appropriate by the Langmuir model [R2 = 0.9987] with qmax = 34.34 mg g −1. Kinetic results showed that Caffeine uptake is following pseudo-second-order. Langmuir and pseudo-second-order are more appropriate in linear and non-linear models. Overall, FB-Fe/Cu is a committed green substance for removal Caffeine from aqueous solutions. Functional parameters affect investigated using the Linear regression analysis, we found them to account for over 98% of the variables affecting the removal procedure.
