POLYMERIC ANIONIC SURFACTANT FOR ELECTROKINETIC CHROMATOGRAPHY - SEPARATION OF 16 PRIORITY POLYCYCLIC AROMATIC HYDROCARBON POLLUTANTS

Electrokinetic chromatography (EKC) with poly(sodium undecylenic sulfa te) (poly-SUS) is utilized to separate environmental pollutants such a s 2-6-ring polycyclic aromatic hydrocarbons (PAHs). Parameters such as pH, concentration of polymeric surfactants, and the use of organic mo difiers were investigated to follow the retention trends of PAHs, A ba seline separation of all 16 PAHs in about 30 min, using 0.50% (w/v) of poly-SUS/12.5 mM sodium phosphate-borate buffer (pH 9.2) with 40% (v/ v) acetonitrile, was possible for the first time in EKC by a single-su rfactant system.
