| Abstract: Sodium, potassium and cesium ion selective PVC membrane electrodes based on bisphenol A type polycrown ethers containing 12-crown-4(1), 15-crown-5(2) and 18-crown-6(3) moities were prepared and their characteristics were investigated. The results showed that three electrods exhibite good Nernstian responses and selectivity to other alkali and alkaline earth cations. |
| Keywords: polycrown ether sodium ion potassium ion cesium ion membrane electrode selectivity coefficient |
