    Abstract: The present invention provides a reference electrode solution containing ammonium salts and phosphonium salts for the potentiometric measurement of pH and method of using the same. The use of the ammonium salts and the phosphonium salts to replace potassium chloride or sodium chloride as reference electrolytes in a standard reference electrode minimizes the formation of precipitates in sample solutions containing cation-sensitive compounds. Disruption of ion flow through the reference electrode is eliminated, and accurate pH measurements may be obtained in solutions that contain compounds having a strong affinity for hard cations.

    Abstract translation: 本发明提供了含有铵盐和鏻盐的参比电极溶液,用于电位测量pH值和使用该方法。 在标准参考电极中使用铵盐和鏻盐代替氯化钾或氯化钠作为参考电解质,使含有阳离子敏感化合物的样品溶液中沉淀物的形成最小化。 消除通过参比电极的离子流的破坏,并且可以在含有对硬阳离子具有强亲和力的化合物的溶液中获得精确的pH测量。
