Use of novel green synthesized C0304-NPs for electrochemical sensing of Pb ions

For the first time, low-cost and green cobalt oxide NPs were synthesized in a one-step process and the synthesized material was used as a catalyst for the electrochemical detection of Pb ions. The synthesized material was characterized by using various techniques such as UV, FTIR and XRD. The green material shows a linear range of detection of 0.9 μM. The electrode fabricated shows an excellent recovery rate in real sample analysis for electrochemical sensing of Pb ions.
