The equation includes the electrical work required for charging the air\/water surface and the work attributable to the configurational entropy in the adsorbed film. By fitting the equation to the experimental data, we determined the binding constant between adsorbed surfactant ion and counterion, and found that the bromide ions, rather than the chloride ions, are preferentially adsorbed by the air\/water surface. Furthermore, it was suggested that the contribution of configurational entropy to the surface tension is predominant in the presence of electrolytes because of the increase in the surface density of surfactant molecules associated with decreasing the repulsive interaction between their hydrophilic groups.<\/jats:p>","DOI":"10.3390\/e12040983","type":"journal-article","created":{"date-parts":[[2010,4,23]],"date-time":"2010-04-23T15:03:03Z","timestamp":1272034983000},"page":"983-995","source":"Crossref","is-referenced-by-count":6,"title":["Effect of Counterion and Configurational Entropy on the Surface Tension of Aqueous Solutions of Ionic Surfactant and Electrolyte Mixtures"],"prefix":"10.3390","volume":"12","author":[{"given":"Youichi","family":"Takata","sequence":"first","affiliation":[{"name":"Faculty of Pharmaceutical Sciences, Tokyo University of Science, 2641 Yamazaki, Noda, Chiba 278-8510, Japan"},{"name":"Center for Colloid and Interface Science, Research Institute for Science and Technology, Tokyo University of Science, 2641 Yamazaki, Noda, Chiba 278-8510, Japan"}]},{"given":"Hiroaki","family":"Tagashira","sequence":"additional","affiliation":[{"name":"Faculty of Pharmaceutical Sciences, Tokyo University of Science, 2641 Yamazaki, Noda, Chiba 278-8510, Japan"}]},{"given":"Atsushi","family":"Hyono","sequence":"additional","affiliation":[{"name":"Faculty of Pharmaceutical Sciences, Tokyo University of Science, 2641 Yamazaki, Noda, Chiba 278-8510, Japan"}]},{"given":"Hiroyuki","family":"Ohshima","sequence":"additional","affiliation":[{"name":"Faculty of Pharmaceutical Sciences, Tokyo University of Science, 2641 Yamazaki, Noda, Chiba 278-8510, Japan"},{"name":"Center for Colloid and Interface Science, Research Institute for Science and Technology, Tokyo University of Science, 2641 Yamazaki, Noda, Chiba 278-8510, Japan"}]}],"member":"1968","published-online":{"date-parts":[[2010,4,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"469","DOI":"10.1016\/0021-9797(74)90393-2","article-title":"and d\/dT measurements on aqueous solutions of 1,1-electrolytes","volume":"49","author":"Johansson","year":"1974","journal-title":"J.
