Abstract

Studies of solubilization of organic contaminants by surfactants are complicated by the fact that the effective surfactant concentration is decreased by partitioning into the organic phase. This paper introduces an experimental setup for surfactant solubilization where the partitioning loss of surfactants is minimized. Using this setup, two anionic (sodium dodecyl sulphate and Spolapon AOS 146) and one nonionic surfactant (Novanik 0633 A) were compared. When comparing solubilization efficacies expressed as multiples of the critical micelle concentration, the two anionic surfactants were able to solubilize a higher amount of polychlorinated biphenyls. For lower surfactant concentrations, solubilization efficacies were similar for all surfactants. However, it is necessary to take into account that the critical micelle concentration of the nonionic surfactant is considerably lower.

Kurzfassung

Studien zur Solubilisierung von organischen Kontaminanten sind kompliziert, aufgrund der Tatsache, dass die effektive Tensidkonzentration durch Partitionierung in die organische Phase abnimmt. Diese Arbeit stellt einen Versuchsaufbau zur Tensidsolubilisierung vor, bei dem der Partitionierungsverlust an Tensiden minimiert worden ist. Unter Verwendung dieses Versuchsaufbaues wurden zwei anionische (Natriumdodecylsulfat und Spolapon AOS 146) und ein nichtionisches Tensid (Novanik 0633 A) gegenübergestellt. Beim Vergleich der Solubilisierungswirksamkeiten, angegeben als Mehrfaches der kritischen Mizellbildungskonzentration, sind die zwei anionischen Tenside in der Lage, höhere Mengen an polychlorierten Biphenylen zu solubilisieren. Für niedrigere Tensidkonzentrationen sind die Solubilisierungswirksamkeiten für alle Tenside ähnlich. Wichtig hierbei ist aber zu berücksichtigen, dass die kritische Mizellbildungskonzentration des nichtionischen Tensids wesentlich geringer ist.
