PVC based membrane of 1,5–diphenylthiocarbazone (dithizone) reveals a Nernstain potentiometric response with the slope of 29+2 mV per decade for Pb2+ over a concentration range (5.0×10–6–1.0×10–2 M). The used electrode was suitable in aqueous solutions in a pH range of 8 to 10. The response time of the electrode is about 15 s and was used for a period of 45 days. The proposed electrode was used in two different applications such as the determination of lead concentration in a part of lead water pipe and as an indicator electrode for potentiometric titration of Pb2+ ions.
