玻璃膜钠离子选择电极有良好的响应性能和选择性,但其内阻高,一般较难制备加工成小型化.中性载体钠电极受氢离子影响小,易于制备和小型化,尤宜用于生化检验中,因而其制备和应用受到了重视.Ammann 等人首先以三甘酰双二苄胺(载体Ⅰ)制成了 PVC 膜钠电极.Fiedler 研究了一些膜溶剂对此中性载体的影响,指出溶剂的介电常数和溶解度参数与电极的性能有 Glass membrane sodium ion selective electrode has good response and selectivity, but its high resistance, generally more difficult to prepare for processing into miniaturization. Neutral carrier sodium electrode is less affected by hydrogen ions, easy to prepare and miniaturization, especially with Therefore, preparation and application of biomolecules have been emphasized in biochemical tests.Ammann et al first made PVC membrane sodium electrode with triglyceride bisdibenzamide (carrier I) .Fiedler studied the effects of some membrane solvents on the neutral carrier The influence of the solvent on the dielectric constant and the solubility parameter and the performance of the electrode is pointed out
