聚冠醚的合成和性质 Ⅵ.聚冠醚为载体的碱金属离子选择性电极

SYNTHESIS AND PROPERTY OF POLYCROWN ETHERS\= ()SODIUM, POTASSIUM AND CESIUM ION SELECTIVE PVC\= MEMBRANE ELECTRODES BASED ON BISPHENOL A TYPE POLYCROWN ETHERS

本文报道以含有１２－冠－４、１５－冠－５和１８－冠－６结构单元的双酚Ａ型聚冠醚为载体的钠、钾和铯离子选择性电极的制备及电极响应特性的研究。结果表明三种电极都有较好的Ｎｅｒｎｓｔｉａｎ响应特性和对碱金属及碱土金属的良好选择性。

; Sodium, potassium and cesium ion selective PVC membrane electrodes based on bisphenol A type polycrown ethers containing 12crown4( 1 ), 15crown5( 2 ) and 18crown6 (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.\=\;
