Green‑Synthesized Calcium Oxide Nanoparticles for Adsorption, Antibacterial Applications, and Alleviating Water Stress in Fenugreek
Waleed Khalid Mahdi, Hassan Abdul Razaq Ali, Aqeel Oudah Flayyih, Falih Hassan Musa and Ahmed Saleem Otaiwi Abstract: In this research, a novel synthesis of CaONPs has been developed via an environmentally friendly, green method. Garlic extract (Allium sativum) was used as a green-reducing and stabilizing agent for CaONPs. The average particle size of CaONPs was approximately 24.42 nm. The synthesized CaONPs were identified by using Fourier transform infrared (FT-IR) spectroscopy, U.V.-vis spectrum, X-ray diffraction (XRD), Field Emission-Scanning Electron Microscopy (FE-SEM), Transmission Electron Microscopy, transmission electron microscopy (TEM), Energy Dispersive X-ray spectroscopy (EDX), Atomic Force Microscopy (AFM), and zeta potential (Zp) analysis. The current study highlights the notable applications for CaONPs. First, an antimicrobial assay revealed a high antibacterial and antifungal activity, with the maximum zone of inhibition observed at different concentrations of CaONPs. Secondly, adsorbent for CaONPs in an aqueous solution containing M+2 ions (Co, Ni, Cu). The removal percentages (R%) were Co (II) 93.47%, Ni (II) 87.58%, and Cu (II) 88.53%. Thirdly, the study of fenugreek under water stress revealed that CaO-NPs positively enhance water stress tolerance.
Keywords: Green Synthesis, Caonps, Antibacterial, Adsorbent, Fenugreek.
