- 中文摘要: A PVC membrane electrode for copper(II) ion based on a recently synthesized Schiff base as a suitable ion carrier was constructed. The electrode exhibits a Nernstian slope of 28.3 ± 0.6 mV per decade of Cu2+ over a wide concentration range of 7.0 ’ 10-6-2.6 ’ 10-2 M with a detection limit of 5.0 ’ 10-6 M in the pH range of 4.2-5.8. The response time is about 10s and it can be used for at least 1 month without any considerable divergence in potential. It was successfully applied as an indicator electrode in the potentiometric titration of copper ions.
