Concentration of polyaromatic hydrocarbons in water to sodium dodecyl sulfate-gamma-alumina admicelle.
Polyaromatic hydrocarbons (PAHs) in water were concentrated into sodium dodecyl sulfate (SDS)-gamma-alumina and di-2-ethylhexyl sodium sulfosuccinate (Aerosol-OT, AOT)-gamma-alumina admicelles. The comparison of the binding constants (Kad[={adsorbed concentration of the solute (mol/g surfactant)}/{the concentration in the bulk aqueous phase (mol/ml)}] indicated almost the same extraction abilities of the both admicelles. However, better and more reproducible recovery was obtained in the concentration of PAHs into the SDS-gamma-alumina admicelle. PAHs in tobacco smoke that were trapped in water were successfully concentrated into SDS-gamma-alumina admicelle for the HPLC analysis.
