| Abstract: | The oxidation of iodide to I
3
–
by oxygen dissolved in water containing HClO4 has been found to be accelerated by  -cyclodextrin (-CD). Among -,  -, and  -CDs, -CD is the most effective mediator for the oxidation reaction of iodide by oxygen. The oxidation rate of iodide is first order in the concentrations of -CD and HClO4, whereas it is second order in the KI concentration.Part of this work was carried out at Department of Physics, Miyazaki Medical College, Miyazaki 889-16, Japan. |
