Abstract
The overlapping of the anodic stripping voltammetric peaks between detached indium from indium tin oxide (ITO)-based electrode and lead ions (Pb2+) was separated with 0.14 V by using bromide ion (Br−) solution which is considered a high and appropriate resolution for analytical purposes. The reduced graphene oxide (rGO) was deposited on the ITO for better metals adsorption and conductivity enhancement. The limit of detection for Pb2+ was calculated as 0.6 ppb with the signal-to-noise ratio of 3 with a linear correlation coefficient of R2 = 0.988.
