Abstract: The interaction between β-cyclodextrin( β-CD) and sodium dodecyl sulfate(SDS) was studied by microcalorimetry, a Host-Guest binding reaction with 1:2 stoichiometry was calculated, the first and second stability constants are 15.50 mol-1 ·Land 7.95 mol-1 ·Lrespectively. According to the experimental results, several related thermodynamic parameters were also obtained and a possible inclusion model was presented as well.

Key words: Microcalorimetry, Inclusion, β-Cyclodextrin, Sodium dodecyl sulfate
