“…The magnetic characteristics of iron particles should make it possible for iron oxide nanoparticles to exist in such close contact with each other, which matched with XPS and XRD. It has also been observed by Rehab et al 67 that iron oxide nanoparticles were agglomerated together. One possible explanation is that the presence of various polyphenols found in extracts have the potential to considerably alter iron oxide nanoparticle form and size 81,82 .…”

“…Iron oxide nanoparticles preparation. As previously reported 67 the synthesis of iron oxide nanoparticles (IONPs) using extract of Clove or green g-Coffee was conducted. Briefly, after constructing an aqueous solution of ferric nitrate (5 ml of 0.3 M Fe (NO 3 ) 3 .9H 2 O), 15 ml of the previously prepared extract were added.…”

Clove and green Coffee (g-Coffee) extracts were used to synthesize green iron oxide nanoparticles, which were then used to sorb Cd2+ and Ni2+ ions out of an aqueous solution. Investigations with x-ray diffraction, Fourier-transform infrared spectroscopy, transmission electron microscopy, X-ray photoelectron spectroscopy, nitrogen adsorption and desorption (BET), Zeta potential, and scanning electron microscopy were performed to know and understand more about the chemical structure and surface morphology of the produced iron oxide nanoparticles. The characterization revealed that the main component of iron nanoparticles was magnetite when the Clove extract was used as a reducing agent for Fe3+, but both magnetite and hematite were included when the g-Coffee extract was used. Sorption capacity for metal ions was studied as a function of sorbent dosage, metal ion concentration, and sorption period. The maximum Cd2+ adsorption capacity was 78 and 74 mg/g, while that of Ni2+ was 64.8 and 80 mg/g for iron nanoparticles prepared using Clove and g-Coffee, respectively. Different isotherm and kinetic adsorption models were used to fit experimental adsorption data. Adsorption of Cd2+ and Ni2+ on the iron oxide surface was found to be heterogeneous, and the mechanism of chemisorption is involved in the stage of determining the rate. The correlation coefficient R2 and error functions like RMSE, MES and MAE were used to evaluate the best fit models to the experimental adsorption data. The adsorption mechanism was explored using FTIR analysis. Antimicrobial study showed broad spectrum antibacterial activity of the tested nanomaterials against both Gram positive (S. aureus) (25923) and Gram negative (E. coli) (25913) bacteria with increased activity against Gram positive bacteria than Gram negative one and more activity for Green iron oxide nanoparticles prepared from Clove than g-Coffee one.

“…From the N 2 adsorption/desorption curve isotherm, as displayed in Figure 3(a), the BET plot (not shown here) and BJH plot (insert image) was drawn to estimate surface area and pore distribution. It revealed the Type IV isotherm curve with an H 3 hysteresis loop (Keluo et al 2018), signifying the groove-shaped pores (i.e., parallel plate-shaped pores) comprising mesopores (Mahmoud et al 2021). The surface area of VS-Fe was 199.189 m 2 /g which is higher when compared to the one synthesized using various plant extracts (Fazlzadeh et al 2017;Bounab et al 2021).…”

“…The as-synthesized VS-Fe nanoparticles were found to be spherical-shaped particles uniformly distributed with lesser agglomeration. The phytochemicals that are present in the VS seed extract are attributed to agglomeration (Wu et al 2015;Mahmoud et al 2021). Some literature has also reported that the Fe ions' magnetic interaction might have caused the agglomeration (Fazlzadeh et al 2017;Katata-Seru et al 2018).…”

<p>The greener approach offers a viable, sustainable and eco-friendly way to synthesize nanoparticles. This study used the seed extract of Vigna stipulacea (VS) as a bioreducing agent to synthesize iron nanoparticles (VS-Fe). The VS seed extract contains polyphenols and lignin content that acted as a bioreducing agent during VS-Fe formation. The Vigna stipulacea-mediated Fe nanoparticles were characterized using UV, XRD, FTIR, EDAX and BET surface analysis. The as-synthesized VS-Fe, comprised of Fe0 phase and Fe hydroxides, had an average crystallite size of 30.65 nm. It possessed a surface area of 199.189 m2/g and magnetic saturation of 11.21 m emu. The VS-Fe exhibited excellent adsorptive behavior during the sequestration of Pb2+ ions from an aqueous environment. The Pb2+ uptake was maximum (96.7%) under the optimal conditions of 60 min contact time, 0.01 g/ 100 mL VS-Fe dosage and pH 6. The equilibrium data of Pb2+ adsorption was more appropriate with pseudo-second-order kinetics (R2 = 0.9903) and Langmuir isotherm (R2 = 0.9941) with qmax of 1020.50 mg/g. Thus, the dominance of chemisorption in Pb2+ removal was revealed. It was further confirmed with the SEM micrograph of Pb-loaded VS-Fe nanoparticles. Overall, this study demonstrated the inexpensive and non-toxic way of synthesizing Fe nanoparticles and their utilization in effectively removing Pb2+ ions from water.</p>
