Surface potential measurements in pentanol-sodium dodecyl sulfate micelles: Surface potential measurements in pentanol-sodium dodecyl sulfate micelles. Hartland, Gregory V.; Grieser, Franz; White, Lee R. (Dep. Phys. Chem., Univ. Melbourne, Parkville 3052, Australia). J. Chem. Soc., Faraday Trans. 1, 83(3), 591-613 (English) 1987. CODEN: JCFTAR. ISSN: 0300-9599. DOCUMENT TYPE: Journal CA Section: 66 (Surface Chemistry and Colloids) The surface potential of SDS micelles was measured by the apparent pKa of a micelle solubilized acid-base indicator. The indicator used was 4-heptadecyl-7-hydroxycoumarin. The surface potentials were measured under conditions of changing surface charge d. and bulk ionic strength and the results analyzed by a Gouy-Chapman-Stern model for the double layer of the micelle. The Na+ counterions in the micelle Stern layer bind between the SO42- head groups. 26038-83-5 and 151-21-3 which are cas registry numbers of substances are two of reagents here. When pentanol is solubilized by the micelle the exptl. potentials are smaller than predicted. The difference is attributed to an increase in the no. of sites for counterion binding at the micelle surface. .
