摘要

The ionic liquid 1-hexyl-3-methylimidazolium hexafluorophosphate is used as a new lipo-philic ionic additive in the polymeric membrane of a solid contact type lead ion-selective electrode. The membrane is deposited on an internal glassy carbon electrode with poly(3-octyl)thiophene as an intermediate layer. The sensor exhibits good analytical parameters: low detection limit of 3.5 × 10~(-9)molL~(-1), Nernstian response slope of 29.8 mV/decade, a wide concentration range of 1 × 10~(-8)-1 × 10~(-1)molL~(-1), short response time of 7 s, and relatively long lifetime of 100 days. The proposed sensor has a working pH range of 4.0-6.9 and excellent selectivity for Pb(Ⅱ) ions over a wide variety of other metal ions. The efficiency of the proposed sensor was demonstrated by its application for direct determination of Pb~(2+) ions in real water samples.
