Summary

This study develops and tests an accessible electrode design for heavy-metal detection. The core contribution is a simple FTO/Nafion/silver nanoparticle platform for detecting Pb(II) and Cu(II).

Key findings

  • The electrode design provides a lower-cost path for electrochemical detection of lead and copper ions.
  • Stabilizing silver nanoparticles with Nafion supports a practical sensing surface.
  • The work emphasizes usable analytical performance with materials that can be implemented without highly specialized infrastructure.

Application

The paper sits at the interface of environmental monitoring, materials chemistry, and practical sensing. Its focus is an accessible measurement platform for metal-ion detection.
