dc.description.abstractThe focus of this study is on synthesizing copper nanoparticles through a green approach, utilizing Terminalia arjuna bark extract. The ultra violet (UV) spectral analysis of copper nanoparticles synthesized through environmentally friendly methods revealed distinct absorption peaks at 287 nm, 575 nm, and 898 nm, indicative of significant light absorption. These peaks elucidate the nanoparticles' optical characteristics, shedding light on electronic transitions and surface plasmon resonance phenomena. Fourier transform infrared spectroscopy (FTIR) analysis displayed various peaks, suggesting vibrations associated with copper nanoparticles and functional groups in T. arjuna bark extract. The X-ray diffraction analysis (XRD) data exhibited characteristic peaks corresponding to metallic copper's crystallographic planes, confirming the formation of highly crystalline copper nanoparticles. Atomic force microscopy results depicted surface morphology and particle size distribution. Copper nanoparticles show promise in mercury degradation due to their high surface area and catalytic activity. They interact effectively with mercury ions through adsorption, reduction, and oxidation processes, leading to sequestration or transformation into less toxic forms. Functionalization enhances their affinity towards mercury, while synergies with other nanomaterials boost efficiency. Green synthesized copper nanoparticles offer an eco-friendly solution for effective mercury remediation, promising advancements in sustainable nanotechnological approaches for global environmental sustainability.
