| Abstract: Sodium, potassium and caesium ion selective PVC membrane electrodes based on nine new bis-crown ethers containing benzo-12-crown-4(1), benzo-15-crown-5(2) and benzo-18-crown-6(3) moieties bridged by pyrimidine ring were prepared and their electrode behaviours were evaluated. The electrodes (1), (2) and (3) exhibited good Nernstian responses and respectively better selectivity with respect to all other alkali and alkaline earth metal cations. |
| Keywords: bis-crown pyrimidine ring sodium ion potassium ion caesium ion membrane electrode selectivity coefficient |
