Importance of hydrophobic interaction in the micellar catalysed diphenyl sulfide oxidation with Iron(III)bipyridyl complex

The effect of various surfactants on the oxidation of diphenyl sulfide (DPS) by iron(III)bipyridyl complex have been studied by observing the increase in absorbance corresponding to iron(II)bipyridyl complex. In this study, sodium dodecyl sulfate (SDS), cetyltrimethylammonium bromide (CTAB) and Triton X-100 are used as the anionic, cationic and non-ionic surfactants respectively. In all the cases rate acceleration has been observed above their critical micellar concentrations and it is more pronounced in the presence of CTAB. The catalysis has been explained by the application of pseudophase model
