Reliability of the Experimental Methods To Determine Equilibrium Constants for Surfactant/Cyclodextrin Inclusion Complexes

摘要: A literature survey reveals that the values of equilibrium constants for inclusion complexes involving surfactants and cyclodextrins can vary by several order magnitude same system when different experimental methods are employed. In this paper we consider problem reliability binding constants. We report here our emf studies cetyltrimethylammonium bromide tetradecyltrimethylammonium with α- β-cyclodextrin compare these data other independent studies. The potential isothermal titration calorimetry as a method to determine is also examined. conclude techniques which yield direct measurements «free» «included» surfactant appear give results consistent
