eng Abstract:
Measurements of the electrophoretic mobility of an anionic dye 4,5-dihydroxy-3-(p-sulfophenylazo)-2,7- naphthalene disulfonic acid trisodium salt (SPADNS), which is a commonly used anionic dye, are described in this contribution. Electrophoretic mobilities of SPADNS were measured in various buffer solutions covering the pH range of 2.4–9.1. Effective electrophoretic mobilities of SPADNS measured in these buffers varied between 50.5 x 10–9 m2/Vs and 60.5 x 10–9 m2/Vs with an average effective mobility of 55.0 x 10–9 m2/Vs.
