Synthesis And Characterization Of Ag And Cuo Nanoparticles Using Plant Extract For The Analysis Of Heavy Metal Removal

Abstract

The removal of presence of heavy metal ions in water is necessary in industrial and academic sectors since heavy metal pollutions can cause several ill-effects. A leaf extract from the Catharanthus roseus plant was used in the current investigation to synthesize Ag and CuO-NPs for the analysis of removal of heavy metals from the aqueous solution. Ag and CuO-NPs was tuned to increase yield by adjusting the salt content, leaf extract content, and time interval.  Ag and CuO-NPs were found using UV-Vis spectroscopy. The wavelength ranges for CuO and Ag-NPs, respectively, were 200-700 nm and 300-700 nm. Utilizing SEM scans, it was discovered that the shape of NPs was spherical and inside 100 nm. Additionally, Z-potential readings for Ag and CuO-NPs were -16.4 mV and - 6.18 mV, respectively. Ag-NPs were found to remove chromium and cadmium with the highest rates, at 47.84% and 5.68%, accordingly. The existing situation of metalloid contamination in water and soil ecosystems can be improved with the aid of our discoveries.
