Abstract

A new method is proposed for measuring association constants and has been used to study the complexation of beta -cyclodextrin with nine substituted benzenes. Computer simulation was conducted to compare the performance of the new method with that of the Benesi-Hildebrand method. It showed that theaccuracy and success rate of the new method were both higher than those ofthe BH method. Hence, the new method is a recommended approach for a convenient and reliable measurement of association constants.
