Research output: Contribution to journalArticlepeer-review


The surface tension of aqueous solution of sodium dodecyl sulfate (SDS) stayed constant by an addition of α-, β-, or γ-cyclodextrin (CD) since the 1:2 inclusion compound, SDS-2CDs, is formed. On the other hand, the addition of [Co(NH3)6](Cl O4)3 into an aqueous solution of the above inclusion compound shows the characteristic drawing of SDS from CDs. The easiness of the drawing is shown as γ-CD > β-CD > α-CD due to the cavity size of CDs.
