Über die adsorptionsfähigkeit wasserlöslicher polymerer verbindungen, insbesondere von polyvinylpyrrolidon

Abstract: Die ilsorptionsfahigkeit von wasserloslichen polymeren Verbindungen, insbesondere von Polyvinylpyrrolidon (PVP) , wurde vor allem fur Farbstoffe quantitativ durch Verteilungsversuche, Dialyseversuche und Elektrophoreseversuche bestimmt. Alle Versuchsmethoden liefern unter bestimmten Voraussetzungen befriedigend ubereinstimmende Ergebnisse. bei Elektrophoreseversuchea am Auftreten einer zusatzlichen neuen Komponente;2. durch Lichtabsorptionsversuche a n der Veranderung des Absorptionsspektrums der 3. durch Visk… Show more

“…This order is consistent with the result reported for cationic surfactants [16], but quite reversed as compared with the one known for anionic surfactants [17]. This kind of phenomenon is also reported in that anionic methyl orange is bound to PVP [18], but a cationic analogue (p-azobenzenetrimethylammonium halide) is not [19]. So it is considered that the antinomy may be rather general, especially with PVP.…”

“…It has been found (2,14,25) that the y-axis intercept values (l/n) are often determined with great uncertainty, implying it has no physical meaning.

“…The interaction with independent binding sites is described by: deduced from the slopes of linear binding plots according to Klotz et al (42) or Scatchard (43). Values of n, however, can be determined only with much uncertainty (44). Their physical relevance is doubtful.…”
