| 摘 要： | 研究发现二元酸酯PVC膜电极对季鏻和季鉮盐均具有能斯特响应。电极的响应机理是由于季鏻、季鉮阳离子的正电中心与电子云密度较大的酯中苯环产生次级力作用所致。

| Abstract: | The quaternary phosphonium and quaternary arsonium ion-selective electrodes prepared with diesters as active substance and plasticizer were investigated. A PVC membrane electrode based on dioctylphtha.late exhibited a Nernstian response to ω-hydroxy-dodecyltriphenylphosphonium bromide and tetraphenylarsonium chloride. The response mechanism of the electrode was studied by using FTIRspectrometry. The response is caused by the secondary weak force between the positive charge center of quaternary phosphonium (or arsonium) and the electronegative benzene ring in diester. |
