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 wide concentration range (5.010-6-1.010-2 M). The electrode is suitable for use 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 showed successful applications to the direct determination of lead in a sample of lead water pipe and also as indicator electrode for potentiometric titration of lead ions with NaCl solution.
