The influence of the anionic surfactant sodium dodecyl sulfate on the rate of the reaction between the cationic form of Nile Blue A and hydrogen peroxide was investigated in the pH range from 5 to 8.5. A retardation of the oxidation of Nile Blue A with hydrogen peroxide of three orders of magnitude was observed at pH 8.5 in the presence of anionic micelles compared to the kinetic data in water. The retardation effect was less pronounced at lower pH values. These effects were explained by the electrostatic interaction of the species involved in the reaction with the negatively charged micellar surface and their effective separation in the vicinity of the micellar surface.

p-n-Butylaniline ([nBA] = 1 × 10−3 M) incorporated in cationic micelles of cetyltrimethylammonium bromide ([CTABr] = 6 × 10−3M) was found to enhance the rate of decarboxylation of oxalacetic acid (OAA) 45-fold while nBA alone only increases the rate six-fold as compared to the rate of spontaneous decarboxylation at the same pH. Anionic micelles of sodium dodecyl sulfate ([SDS] = 6 × 10−3 M) completely inhibited the catalytic effect of nBA. Together with the effects of added salts and the change of pH on the rate of the reaction the role of micelles in the decarboxylation of OAA is discussed.

The solubility of chlorophenols as affected by surfactant was investigated. Three kinds of surfactant, sodium dodecyl sulfate, Triton X-100, and Brij 35, were utilized. The solubilization of chlorophenols by surfactant follows the order of 2,4,6-trichlorophenol > 2,4-dichlorophenol > 2,6-dichlorophenol > 2-chlorophenol; and the critical micelle concentration is an important index. The adsorption reactions of 2,4-dichlorophenol and 2,4,6- trichlorophenol onto hydrous montmorillonite in the presence of surfactant were examined. The presence of surfactant decreased the adsorption of chlorophenols significantly. The roles of hydrophobicity of chlorophenols in solubilization and adsorption behaviors are discussed.
