液膜和PVC膜电极一般都采用含一定浓度主要响应离子的溶液作内充液,在膜内侧以离子导电方式建立一个恒定的电位。因此,每一种电极都需要它自己的内充液。若对于某一类电极能有通用的内参比体系,对于生产与使用都将带来方便。离子缔合型电极的活性材料(如季铵盐、碱性染料、四苯硼酸盐等)一般是“广谱”的,即能对多种离子产生Nernst响应。在本文前三报中,我们发现对于离子缔合型的阴 Liquid membrane and PVC membrane electrodes are generally used with a certain concentration of the main response to the ion solution as a filling solution, the membrane inside the ionic conductivity to establish a constant potential. Therefore, each electrode requires its own fill. If for a certain type of electrode can have a common internal reference system, for the production and use will bring convenience. The active materials of ion-association electrodes (such as quaternary ammonium salts, basic dyes, tetraphenylborate, etc.) are generally “broad-spectrum” in that they produce a Nernst response to a wide range of ions. In the first three papers, we found that the ion-associated anion
