Synthesis of silver nanoparticles from natural derived embelin compound and their uses in mercury degradation under solar light

Abstract

The present study deals with the isolation of embelin compound from Embelia ribes (Burm.f.). The isolated compounds were confirmed by UV/Vis spectrophotometer, 1H NMR and 13C NMR spectra. In absorption at 275nm in UV/Vis spectra, peak range at 5.7ppm in 1H NMR and peak value at 28.52, 29.35, 31.73ppm in 13C NMR to confirmed the isolated compound are embelin. This isolated compound used as a reducing agent for silver nanoparticles synthesis. The synthesized En-AgNPs were morphologically and structurally confirmed by UV/Vis spectrophotometer, FT-IR, SEM, EDAX, and XRD. The synthesized silver nanoparticles are spherical in shape with the size of <100nm. The embelin based silver nanoparticles used to degrade the toxic metal like mercury under solar light. The toxic metal mercury was degraded within 60 minutes by En-AgNPs under solar photo catalytic degradation.
