Dodecyl Sulfate

The relative reactivity of the nitroxides tetramethylpiperidin-N-oxide, 5-DOXYL-stearic acid and 12-DOXYL-stearic acid in the quenching of excited states in sodium dodecyl sulfate micelles has been examined. 12-DOXYL-stearic acid is a better quencher in the case of very hydrophobic sensitizers, such as pyrene singlets or phenanthrene (singlet or triplet states). The converse is true for the hydrophilic xanthone triplet or excited Ru(bipy)32+. The results support the idea of preferential solubilization in different regions of the micelle and provide a method for probing this preference.

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.
