manuscript describes synthesis of silver nanoparticles (AgNPs) by utilizing
beet juice. These synthesized AgNPs were coated onto the working carbon
electrode which involved an electrochemistry experiment utilizing Square Wave
Anodic Stripping Voltammetry (SWASV) to detect heavy metals lead and cadmium in
solution. For centuries, silver has been known to have effective bactericidal
properties and has been used for the treatment for infection in burns, open
wounds, and chronic ulcer. The purpose of this lab experiment study was to
synthesize and utilize the AgNPs using a green synthesis technique from beets
which are nontoxic to modify the carbon working electrode to electrochemically
detect toxic metals, major heavy metals polluting waters. This sensor has been
developed for the sensitive and selective detection of Pb and Cd by Square Wave
Anodic Stripping Voltammetry, SWASV.
