Sodium Ion-Selective Membrane Electrode Based on Dibenzopyridino-18-Crown-6

2004 Bulletin of the Korean Chemical Society (Print)  
A sodium ion-selective electrode based on dibenzopyridino-18-crown-6 as membrane carrier was successfully prepared. The electrode exhibits a Nernstian response for Na + ions within the concentration range of 1.0 × 10 −4 -1.0 × 10 −1 M. The response time of the sensor is 20 s. The sodium ion-selective electrode exhibited comparatively good selectivities with respect to alkali, alkaline earth and some transition metal ions.
