Electrochemical Detection of Arsenic in Various Water Samples

Abstract

Nano Au-crystal violet (CRV) film has been fabricated on glassy carbon electrode (GCE) and indium tin oxide glass electrode (ITO) using cyclic voltammetry. The nano Au-CRV film modified GCE has been successfully employed for the detection of arsenic in lab and real drinking water sources like mineral water, spring water and tap water samples. The Nano Au-CRV film modified GCE successfully detects the arsenic in the linear range of 4 - 40 µM with the detection limit of 0.20 µM in lab samples. The proposed film successfully detects the arsenic in the commercial drinking water sources with sufficient detection limits.
