The modified nano-CdO/Ag-CdO-carbon paste electrodes were developed for electrochemical detection of mercury (Hg+) heavy metal. The synthesized samples were well characterized through PXRD (Powder X-ray diffraction), SEM-EDAX (Scanning Electron Microscopy-Energy Dispersive X-ray Analysis), XPS (X-ray photo-electron spectroscopy), FT-IR (Fourier transform Infra-Red), and UV-Visible spectroscopy. The Ag-CdO modified electrode endowed with higher sensing current and Csp (188F/g) than pure CdO NPs (94.6F/g) measured by Linear Sweep (LS), Cyclic Voltammetric (CV) and Electrochemical Impedance Spectral (EIS) techniques. The excellent electrochemical sensing action of developed Ag-CdO electrode was examined on heavy metal Hg+ ions at 15 mM scan rate in 0.1M KCl. The linear relationship of sensing measurements with smaller concentration (15 mM) was observed with its increased current (+ 1.64 104 A/cm2 at 1 mM) at 30 mV/s. LOD of CdO and Ag-CdO electrodes (Hg+Oxid) were found at 1.91 mM &amp; 2.41 mM (Hg+Red) respectively with maximum sensitivity at -0.006V. LOQ of CdO and Ag-CdO electrodes (Hg+Oxid) were 5.78 mM &amp; 6.98 mM respectively with maximum sensitivity at -0.006V. The antibacterial measurements of prepared samples were examined for their susceptibility to inhibit the growth of gram-negative (Escherichia coli) and gram-positive (Staphylococcus aureus) bacteria. Thus, the synthesized Ag-CdO electrode provides a new insight for determining the concentrations of critical pollutants and processing the various nanoparticles for sensing of cyanogenic heavy metals.
