Selectrode—the universal ion-selective electrode
TL;DR: The correlation between extraction data and electrode behaviour assisted in explaining the vital properties of organophosphate-based calcium electrodes, and in suggesting a new liquid ion exchanger, di-(n-octylphenyl) phosphoric acid as discussed by the authors.
Journal ArticleDOI
SelectrodeTM-the universal ion-selective electrode : Part III. Concept. Constructions and materials
TL;DR: In this article, the concept and construction of a multipurpose electrode, the selectivity of which can easily be changed, is described and the change of electrode response is achieved by using various electroactive materials, which can be either solid (solid-state selectrode) or liquid (liquid-state Selectrode).

The liquid-state ion-sensitive electrode
J. Ru̇žička,J.Chr. Tjell +1 more
TL;DR: In this article, a series of ion-selective electrodes based on metal dithizonates is discussed and a theory to explain their behavior is proposed, where the higher the extraction constant of the metal Dithizonate, the greater is the selectivity of the electrode prepared from it for the particular metal involved in the extraction system.
