Description: Sodium polyacrylate (NaPA) is not only well known for the high water absorbability, but also for its electrochemical performance. As knowing NaPA, which is normally used as a polymer binder or cupping reagent, is an anionic polyelectrolyte with negative charge. In this study, NaPA is investigated to develop an Ag/AgPA internal redox system (IRS) for practical reference electrodes (REs). Moreover, the ‘waterlock’ property of NaPA was also applied to lock and gelatinize the inner solution to prevent liquid junction (LJ) between the RE’s inner solution and testing samples. This type of RE has advantages of low cost, easy construction and are suitable for general utilization. The characteristics, including stability, reproducibility and the influence of ionic strength, were studied and validated.
