This study introduces a new cobaltabis(dicarbollide)-doped polypyrrole film electrode for pH sensing. Modified with PVC, the electrode offers rapid, low-cost, and effective pH measurements comparable to commercial glass electrodes.

Area of Science:

  • Electrochemistry
  • Materials Science
  • Analytical Chemistry

Background:

  • Development of novel electrochemical sensors for accurate pH determination is crucial in various scientific fields.
  • Polypyrrole (PPy) is a conducting polymer with potential applications in sensor technology.
  • Cobaltabis(dicarbollide) doping offers unique electrochemical properties.

Purpose of the Study:

  • To synthesize and characterize cobaltabis(dicarbollide)-doped polypyrrole (PPy) films on glassy carbon electrodes.
  • To evaluate the potentiometric response and suitability of the new material for pH measurements and acid-base titrations.
  • To improve the response time of the sensor using a template-assisted method.

Main Methods:

  • Galvanostatic deposition of cobaltabis(dicarbollide)-doped PPy films on glassy carbon electrodes.

  • Potentiometric investigation in various pH buffers and acid-base titrations.
  • Fabrication of a modified electrode using a polyvinyl chloride (PVC) template to enhance response time.

    • Main Results:

    • The cobaltabis(dicarbollide)-doped PPy films exhibit a quasi-Nernstian response (approx. 50 mV/pH unit) over a wide pH range (3-12) with high linearity (r2 ≈ 0.98).
    • The initial electrode design showed slow response times, limiting its use in multiprotic titrations.
    • Employing a PVC template significantly improved the response time by forming PPy wires, resulting in a rapid and cost-effective sensor.

    Conclusions:

    • Cobaltabis(dicarbollide)-doped PPy films are promising materials for potentiometric pH sensing.
    • The PVC-templated PPy electrode offers a rapid, low-cost, and high-performance alternative to commercial glass electrodes.
    • This enhanced sensor is suitable for general pH measurements and monoprotic titrations.
