Nonionic and ionic surfactants at an interface
Abstract. A Ginzburg-Landau theory is presented on surfactants in polar binary mixtures, which aggregate at an interface due to the amphiphilic interaction. They can be ionic surfactants coexisting with counterions. Including the solvation and image interactions and accounting for a finite volume fraction of the surfactant, we obtain their distributions and the electric potential around an inte...
متن کاملMicellar Solutions of Ionic Surfactants and Their Mixtures with Nonionic Surfactants: Theoretical Modeling vs. Experiment1
Here, we review two recent theoretical models in the field of ionic surfactant micelles and discuss the comparison of their predictions with experimental data. The first approach is based on the analysis of the stepwise thinning (stratification) of liquid films formed from micellar solutions. From the experimental step wise dependence of the film thickness on time, it is possible to determine t...
متن کاملToxicity of nonionic surfactants
Nonionic surfactants are amphilic chemicals that enhance desorption and bioavailability by increasing solubility and dispersion of poorly soluble hydrocarbons and oils. This study was conducted to determine the toxicity of commercial nonionic surfactants by using the Microtox Acute Toxicity test which is a rapid, simple test for toxicity. The test uses the luminescent bacterium V. fischeri as t...
متن کاملNonionic surfactants in paper electrophoresis.
i-i E1IE HAVE BEEN a number of reports iii the literature regarding the use of surface active agents in zone electrophoretic studies of 1)100(1 serum proteins and hpoprotems. Ardr (1) found that cationic detergents formed, with serum protenis, complexes that migrated like $-lipoproteins, while aiiionic detergents formed complexes that clectrophoretically resembled -1ipoproteins. More recently, ...
متن کاملSimultaneous determination of cationic surfactants and nonionic surfactants by ion-association titration.
A simultaneous determination of cationic and nonionic surfactants has been developed using ion-association titration. Tetrabromophenolphthalein ethyl ester (TBPE) was used as an indicator. Benzalkonium reacted with TBPE to form a blue ion-associate in the organic phase. When tetrakis(4-fluorophenyl)borate was added dropwise to the solution, the color of the organic phase turned to yellow at the...
