Characterization and application of molecular binary mixed molecular micelles of sodium 10-undecenyl sulfate and sodium N-undecenyl leucinate as pseudostationary phases in micellar electrokinetic chromatography

► Molecular mixed micelles of a sulfated and a leucinated surfactants were prepared. ► These molecular binary mixed micelles were applied as pseudostationary phases in MEKC. ► Elemental analysis data reveal that the composition of micelles remains the same. ► These molecular micelles were characterized using a variety of analytical tools. ► Their partial specific volumes, aggregation number, polarity, phase ratios were determined.
