The elemental depth profiles of these IL mixtureswere derived fromthe observed HRBS spectra through spectrum modeling. By comparing the observed depth profiles with those of pure ILs, the surface mole fractions of constituent ILs were estimated. We found a general tendency that larger IL is enriched at the surface. The observed surface enrichment can be reasonablywell reproduced by a simple thermodynamic calculation based on the Sprow-Prausnitz equation. A slight deviation from the calculated resultwas ascribed to the nonideal behavior of the IL mixtures, which was neglected in the calculation.
