| 摘要: 合成了九种用嘧啶环桥联的新的双冠醚,其中分别含有苯并-12-冠-4、(1、47)、苯并-15-冠-5(2、5、8)和苯并-18-冠-6(3、6、9)。用它们作为载体分别制成钠、钾和铯离子选择性电极,测定了电极的选择性系数。结果表明,电极(7)(8)(9)具有较好的性能。 |

| Abstract: Sodium, potassium and caesium ion selective PVC membrane electrodes based on nine new bis-crown ethers containing benzo-12-crown-4(1, 4,7), benzo-15-crown-5(2,5,8) and berzc-18-crown-6(3,6,9) moieties bridged by pyrimidine ring were prepared and their electrode behaviours were evaluated.The electrodes (1,4,7), (2,5,8) and (3,6,9) exhibited respectively better selectivity of sodium, potassium and caesium ions than all other alkali and alkaline earth metal cations. |
| Keywords: bis-crown pyrimidine ring sodium ion potassium ion caesium ion membrane electrode selectivity coefficient |
