Heavy metal analysis in tai lake water sample based on vanadium oxide-polypropylene carbonate modified electrode

Abstract

Heavy metal ions are detrimental risks to human health due to their high toxicity. Electrochemical determination of heavy metal ions is an effective and low cost approach for environmental sample analysis. In this work, we prepared a vanadium oxide polypropylene carbonate for indium tin oxide electrode surface modification. The electrochemical property of the vanadium oxide polypropylene carbonate was studied cyclic voltammetry. The modified electrode showed an excellent performance towards detection of Cd2+, Pb2+, Cu2+, and Hg2+. The concentration measurement of heavy metal ions using proposed electrode are in good agreement with the previous reports. In addition, the proposed electrochemical sensor was applied for heavy metal content analysis of Tai Lake water samples.
