Lead ion selective electrode; Potentiometric titration; INDICATOR ELECTRODE
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.
