Zur Wirkung kationischer Tenside auf das Spektrale Verhalten des sauren Triphenylmethanfarbstoffs Pentachrom Azurblau und seiner Metall-(III)-Komplexe - Micelleffekt oder ternäre Komplexbildung?

The Effect of Cationic Detergents on the Spectral Properties of Pontachrome Azur blue and its Metal(III)-complexes - Micell Effect or Ternary Complex Formation? The results of studies of the metachromasy effect of pontachrome azur blue and its lakes, preferably with aluminium, and hexadecyl-, tetradecyl-, dodecyl- and decyltriethyl-ammonium-bromide, respectively can be explained on the basis of ternary complex formation. The surfactants can be applied at concentrations far below its critical micelle concentrations thus excluding micelle effects.
