Overview

Electrochemical sensors utilizing CdO and Ag-CdO NPs demonstrate improved mercury detection sensitivity, suggesting new pollutant monitoring options.

Key Points

  • The Ag-CdO modified electrode exhibits higher sensitivity for detecting mercury ions compared to pure CdO.
  • Maximum current of +1.64 × 10-4 A/cm² was recorded at a concentration of 1 mM of mercury, improving detection capabilities.
  • Characterization techniques, including PXRD and SEM-EDAX, confirmed the successful synthesis of modified nanoparticles.
  • Antibacterial tests show the potential of synthesized Ag-CdO electrodes against harmful bacteria strains.
