Abstract

We report the formation of gold nanoparticles on indium tin oxide conducting glass (ITO) surface via electrodeposition method at room temperature. The prepared nano-Au electrodes has been fabricated for sensitive detection of Pb, and showed highly selective response toward Pb. The electrochemical detection of Pb were determined by differential pulse stripping voltammetric (DPSV). The nano-Au electrochemical sensor could detect Pb from 0.5 to 10 M with detection limits of 0.06 M (S/N= 3) and sensitivity of 0.27996 mA M. The proposed sensor is simple, reliable, sensitive, selective, and low-cost, thus holds potential for practical application in Pb detection.
