缔合型离子选择电极的研究

STUDIES ON ION SELECTIVE ELECTRODES BASED ON ION ASSOCIATION

本文总结了我院十年来对缔合型离子选择电极的研究成果。叙述了我院研制成的14种缔合型离子选择电极的性能和特点。探讨了缔合型离子选择电极的一些规律,如活性材料结构和浓度对电极性能的影响、离子相对选择性的规律、通用内参比体系和通用电极的研究等。总结了缔合型离子选择电极的应用研究成果,包括直接测定离子浓度、作为电位滴定的指示电极、作为催化动力学法的指示电极等。

Studies in this institute on ion selective electrodes based on ion asso- ciation (IAISE) are summarized. 14 kinds of IAISE were prepared during the past decade and their main characteristics are presented. Some regularities in preparation and application of IAISE, i. e., effects of structure and concentration of ion exchan- gers, relative selectivity sequence for various ions, the general internal reference system and general electrode, are developed. Applications of IAISE in analysing non-ferrous metals, rare metals and other materials, including direct determination of ions, indirect determination of ions by potentiometric titration and kinetic potentiometry using IAISE as indicator electrodes, are illutrated.
