“…52 A measurement of 1361–1446 cm −1 corresponds to the frequency of CC aromatic vibrations. 53 The measured bend at 1033 cm −1 is attributed to a single vibration of the C–O bond. In the sample 1 and sample 2, the emergence of FTIR band around 2350 cm −1 could be assigned to asymmetric stretching of CO 2 which might be involved during the preparation and measurement of FTIR analysis.…”

In the present work, an extract of Salvia officinalis leaves was used to synthesize an alumina/NiO nanocomposite by the coprecipitation method. First, the shape and surface content of the synthesized adsorbent were determined. Scanning electron microscopy images showed the production of nanospheres and nanorods with sizes between 35 and 50 nm. X-ray diffraction measurement revealed strong, high-intensity peaks, confirming the preparation of a highly crystalline alumina/nickel oxide nanocomposite. Then, the pure nanoalumina, nickel oxide, and functionalized alumina/nickel oxide nanocomposite for water defluoridation were investigated under various conditions, for example, stirring period, pH, and initial fluoride concentration. Defluoridation with greener alumina, nickel oxide, and alumina/nickel oxide nanocomposite lasted 120 min at adsorbent dosages of 0.8 g/L in a pH 7 solution. The adoption process for the three sorbents matches the Langmuir adsorption isotherm. The process dynamics were explored using pseudo-second-order and first-order kinetics. The water quality after treatment met drinking water requirements, proving the viability of using nanoparticles for drinking water defluoridation. This work confirmed effective water defluoridation in the crystalline phase using synthesized nanoalumina, nickel oxide, and their nanocomposite, which highlights their importance for future drinking water defluoridation.

Titanium dioxide nanoparticles (TiO 2(Aq) and TiO 2(Et) ) were synthesized by treating titanium tetraisopropoxide (TTIP) with the aqueous/ethanolic extracts of Morus nigra leaves. The synthetic method is an environmentally friendly, inexpensive and beneficial as the plant leaves act as stabilizing and reducing agents. The obtained NPs were characterized by FTIR spectroscopy, X-ray diffraction (XRD) analysis, scanning electron microscopy (SEM) and Raman spectroscopy. The crystallite sizes of TiO 2(Aq) and TiO 2(Et) NPs were found to be 0.17 and 0.076 nm, respectively. FTIR spectroscopy have shown the coating of plant material upon the surface of nanoparticles. SEM analysis has shown the round shape and irregular surface morphologies of nanoparticles. The bio-synthesized TiO 2 NPs displayed negligible toxic hemolytic effects and had a little inhibition of Staphylococcus aureus and Proteus Mirabilis bacteria as compared to ciprofloxacin.
