近年来,在离子选择性电极领域中的工作主要集中对电极膜中所包括的过程的基本了解以及对新的敏感体的设计。新的离子选择性电极发展的主要方向是液膜电极、气敏电极和酶电极。而在液膜电极中,中性载体离子选择性电极的研究工作是非常活跃和有前途的。正如 G.A.Rechnitz 等人所指出:“在膜相中采用中性载体是液膜离子选择性电极中的一个 In recent years, work in the field of ion-selective electrodes has focused mainly on the basic understanding of the processes involved in electrode films and the design of new sensitive bodies. The main development of the new ion-selective electrode is the liquid membrane electrode, gas sensing electrode and enzyme electrode. In the liquid membrane electrode, neutral carrier ion selective electrode research work is very active and promising. As G. A. Rechnitz et al. Point out: "The use of a neutral support in the membrane phase is one of the membrane-electrode-selective electrodes
