Abstract
The difference in solubilization phenomena exhibited when polar and nonpolar oily materials are solubilized by Sodium dodecyl sulfate (SDS) has been investigated by measuring the electrophoresis, the diffusion, and the viscosity. Based on the assumption that the micelle is spherical the effective specific volume, the effective radius, the ζ-potential and the number of effective charges have been calculated. At the limit of solubilization all four quantities were larger for octanoic acid than for octane. The electrophoretic mobility of the micelle, |UM|, increased when octanoic acid was solubilized, in contrast to a decrease observed in the solubilization of octane.Keywords
