The oxidation of Fe(bpy) 2 2+ by peroxodisulphate (bpy = 2,2′‐bipyridine) has been studied in a variety of sodium bis (2‐ethylhexyl)sulfosuccinate(aerosol‐OT or AOT)‐oil‐water microemulsions by changing the nature of the oil phase, the surfactant concentration, and the molar ratio w = [H 2 O]/[AOT]. Kinetic results show that the influence of surfactant concentration is due to a dilution effect. On the other hand, the comparison between the reaction rate in conventional aqueous solution with that in AOT w / o microemulsions seems to indicate that the iron(II) species is distributed between the aqueous phase and the interphase. © 1995 John Wiley & Sons, Inc.
