Abstrakt: The surface tension of aqueous solution of sodium dodecyl sulfate (SDS) stayed constant by an addition of a-, ß-, or ?-cyclodextrin (CD) since the 1:2 inclusion compound, SDS–2CDs, is formed. On the other hand, the addition of [Co(NH3)6](ClO4)3into an aqueous solution of the above inclusion compound shows the characteristic drawing of SDS from CDs. The easiness of the drawing is shown as ?-CD > ß-CD > a-CD due to the cavity size of CDs.
