Micellar solubilization in strongly interacting binary surfactant systems

摘要: The apparent partition coefficient P of barbituric acids between micelles and water has been determined in mixed binary surfactant solutions from solubility measurements the whole micellar composition range. systems chosen ranged strongly interacting system dodecyltrimethylammonium chloride + sodium dodecyl sulfate to weakly such as benzyldimethyltetradecylammonium tetradecyltrimethyammonium chloride. In all cases studied, micelle formation is unfavorable solubilization. A correlation found unlike surfactants interaction energy, measured by regular solution parameter {beta} solute change upon mixing. By use literature data on solubilization solutions, it shown that for solutes which are solubilized surface adsorption generally governed sign amplitude {beta}.
