Separation of aromatic hydrophobic sulfonates by micellar electrokinetic chromatography.
Two different buffer systems for the separation of 12 aromatic hydrophobic sulfonates by micellar electrokinetic chromatography (MEKC) were developed. The following buffer systems were used: aqueous phosphate buffers containing either cetyltrimethylammonium bromide (CTAB) or sodium dodecyl sulfate (SDS). Eleven aromatic sulfonates were simultaneously separated in less than 35 min employing 20 mM phosphate buffer, pH 7.0 containing 50 mM SDS and 10% of acetonitrile.
