The binding of ionic surfactants (S) to {alpha}- and {beta}-cyclodextrins (CD) has been investigated using surfactant-selective electrodes. These electrochemical measurements have shown that S(CD) and S(CD){sub 2} inclusion complexes are formed between sodium dodecyl sulfate and both {alpha}- and {beta}-cyclodextrins and also between dodecyltrimethylammonium bromide and {alpha}-cyclodextrin. On the other hand, the cationic surfactant only forms a 1:1 complex with {beta}-cyclodextrin. From the data the equilibrium binding constants for the formation of each of the complexes have been evaluated. 29 refs., 5 figs., 1 tab.
