  • Acid Red 88 dye anion-selective electrode
    Simončič, Barbara ; Špan, Jože, 1926- ; Vesnaver, Gorazd
    An ion-selective membrane electrode selective to the Acid Red 88 (C.I. 15620) dye anion has been constructed. This electrode, with the Acid Red 88 dye anion-cetylpyridinium cation carrier complex ... incorporated within a poly(vinyl chloride) gel membrane, permits direct determination of the dye monomer concentration. In this work its fabrication, general performance and selectivity are described. The selectivities have been obtained by a mixed solution method for the Acid Orange 7 (C.I. 15510), Acid Red 13 (C.I. 16045) and Acid Blue 25 (C.I. 62055) interfering anions. The selectivity coefficients suggest that the dye electrode is not sensitive to interfering dye anions of similar structure and different charge or size.
