“…Synthesis of Fe/Cu bimetallic nanoparticles was carried out by reduction of FeSO 4 ·7H 2 O and CuSO 4 ·5H 2 O aqueous mixture using sodium borohydride, following the method of Morales‐Luckie et al . First, 5 mmol L −1 aqueous solutions of FeSO 4 .7H 2 O and CuSO 4 .5 H 2 O were prepared separately using DI water.…”

BACKGROUND: While various iron-based nanomaterials have been studied for the removal of arsenic from groundwater or its immobilization in soils, this study focuses on the applicability of iron/copper bimetallic nanoparticles for removal of arsenic from synthetic contaminated waters. In order to determine the effectiveness of these nanoparticles for arsenic removal, after synthesis, various sorption tests were performed with aqueous arsenic solutions.

“…The electrons are transferred and the reduction process occurs, leading to the formation of AgNPs. It is well known that flavonoids also prevent agglomeration and stabilize the AgNPs in aqueous solution [16,[21][22][23]58]. This makes Table 1 shows, for the five types of microorganisms, the minimum inhibitory concentration and the concentrations in milligrams/mL, as well as the maximum effective concentration of the AgNPs.…”

Syzygium aromaticum (clove) has been used as a dental analgesic, an anesthetic, and a bioreducing and capping agent in the formation of metallic nanoparticles. The main objective of this study was to evaluate the antimicrobial effect in oral microorganisms of biogenic silver nanoparticles (AgNPs) formed with aqueous extract of clove through an ecofriendly method “green synthesis”. The obtained AgNPs were characterized by UV-Vis (ultraviolet-visible spectroscopy), SEM-EDS (scanning electron microscopy–energy dispersive X-ray spectroscopy), TEM (transmission electron microscopy), and ζ potential, while its antimicrobial effect was corroborated against oral Gram-positive and Gram-negative microorganisms, as well as yeast that is commonly present in the oral cavity. The AgNPs showed absorption at 400–500 nm in the UV-Vis spectrum, had an average size of 4–16 nm as observed by the high-resolution transmission electron microscopy (HR-TEM), and were of a crystalline nature and quasi-spherical form. The antimicrobial susceptibility test showed inhibition zones of 2–4 mm in diameter. Our results suggest that AgNPs synthesized with clove can be used as effective growth inhibitors in several oral microorganisms.

“…Besides these peaks, there are others less intense peaks corresponding to iron oxides nanoparticles. Peaks found related to copper have the lowest intensity, this may have two explanations, the first one is because the amount of copper in the bymetallic system is very low, and the second one is associated to the plausible formation of a Fe-Cu oxide nanoparticles, in which it has already been studied by XRD that copper peaks usually do not appear [17].…”

A B S T R A C TFe-Cu oxides nanoparticles were embedded on tuffite (TUF) mineral by means of a simple immersion-ion impregnation, followed by a reduction reaction, methodology. TUF/Fe-Cu nanocomposite characteristics were investigated by XRD, TEM, BET, SEM, FT-IR spectroscopy and pH zpc method. Fe-Cu nanostructures with mean sizes between 10 and 20 nm were effectively supported on TUF. Because of its functional properties, the nanocomposite was studied as adsorbent material for the degradation of malachite green (MG) organic dye in aqueous solution. The adsorption kinetic data was well-fitted to pseudo first-order model, indicating physisorption as the main mechanism of adsorption. High pH and temperature of the solution favored malachite green adsorption. The adsorption process was spontaneous and endothermic. In comparative sorption experiments with different dyes, the nanocomposite showed better removal capacities for cationic and basic than for anionic and acid dyes. Langmuir, Freundlich, Langmuir-Freundlich and Temkin models were applied to evaluate the isotherms, resulting in an adsorption capacity of 376.66 mg/g, which is above most of the adsorbent materials so far employed for malachite green degradation in aqueous solution. Therefore, this novel, easy to prepare and low-cost nanocomposite proved to have synergic functionality as an efficient adsorbent material for cationic organic dyes.
