Abstract

In this research work,siver silver nanoparticles (AgNPs) was were synthesized using calotropis procera leaves leaf extract. The Fourier Transformed Infrared (FT-IR) result of calotropis procera shows functional groups that are capable of reduction and stabilization of the AgNPs nanoparticles such as alcohols which is suitable for the synthesis of AgNPs. The produced nano adsorbent was characterized using X-ray powder diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR) and energy dispersive infrared(EDX). The SEM micrographs revealed well well-dispersed silver nanoparticles (AgNPs) and the XRD showed a crystalline nanoparticle. The FT-IR shows a carbon stretched region signifying aldehydes while EDX shows that carbon and hydrogen having have higher percentage concentrations which depict a carbonated and hydrolysed AgNPs. Percentage removal of chromium was 97.58% at the highest dose of 1.0g.
