冠醚中性载体膜锂离子选择性电极,近年来有较大的发展,受到人们的重视,它们主要是以14—冠—4,12—冠—4及其衍生物为活性物质,该类型电极由于其活性物质结构的特性,对Li~+有较大的浓度范围的Nernst响应,对其它一价离子有较好的选择性。为了进一步改进电极性能,提高测定的选择性以扩大应用,本文合成了苯并12—冠—
Crown ether neutral carrier membrane lithium ion selective electrode, in recent years have been more developed, people have taken seriously, they are mainly 14-crown -4,12-crown-4 and its derivatives as the active substance, the type Due to the structure of the active material, the electrode has a larger concentration range of Nernst response to Li ~ + and a better selectivity for other monovalent ions. In order to further improve the electrode performance, increase the selectivity of the determination to expand the application, the synthesis of benzo 12-crown-
