POLY(SODIUM-10-UNDECYLENATE) AS PSEUDO-STATIONARY PHASE IN THE SEPARATION AND QUANTIFICATION OF POLYAROMATIC HYDROCARBONS BY MICELLAR ELECTROKINETIC CHROMATOGRAPHY

In this work we reported the synthesis of different molar mass fraction of poly(sodium-10-undecylenate) (PSU), and its subsequent utilization as pseudostationary phase in the separation of a mix of 4 polyaromatic hydrocarbons (PAHs); naphthalene (NAPH), fluorene (FLU), phenantrene (PHEN) and pyrene...
