| Résumé : |
Experimental studies have been conducted to explore the interfacial tensions in an acid-free oil/alkali/surfactant system, and sodium hydroxide is used as the alkali chemical. The influences of salt and alkali on the interfacial activity of oil/surfactant systems were studied by the measurement of interfacial tensions and partition coefficients. The results showed that in an appropriate concentration range, an ultra-low interfacial tension could be obtained in the acid-free oil/alkali/surfactant system, and compared with the salt; the function of alkali for lowering interfacial tensions and improving partition coefficients is more significant. |
