| Abstract
| - Data have been assembled from the published literature on the water-to-micellar sodium dodecyl sulfate(SDS) partition coefficient data for more than 200 compounds and on the gas-to-micellar SDS partitioncoefficient data for more than 140 compounds. It is shown that an Abraham solvation equation with onlyfive descriptors can be used to correlate the observed partition coefficient data to within a standard deviationof 0.22 log units. Micellar electrokinetic chromatographic (MEKC) retention factor data measured on amicellar SDS pseudostationary phase was also gathered from the literature. The water-to-micellar SDS partitioncoefficient and MEKC retention factor data were combined into a single database and correlated with theAbraham model. The derived correlation described the 486 experimental values to within a standard deviationof 0.15 log units. The micellar SDS system has been compared to various liquid phases in terms of solubilityof gases and vapors and has been shown to be a very selective systemmore so than room-temperatureionic liquids.
