“…Modern liquid chromatography (LC) offers many advantages for the analysis of PAHs in environmental samples (4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17). Many of the PAHs suspected of mutagenic or carcinogenic activity contain four to six fused rings.…”

An analytical method is described for the determination of 16 polycyclic aromatic hydrocarbons (PAHs) in aqueous samples. These 16 PAHs are of environmental concern, since 15 of them are included on the EPA Priority Pollutant list. After liquid-liquid extraction, the concentrated samples are analyzed by reversed-phase liquid chromatography with fluorescence detection. These 16 PAHs are almost fully resolved chromatographically, so they can be determined in a single run. The method is applied to the analysis of several environmental water samples and several of these compounds are quantitated at concentrations below 10 ng/L in the original sample.

Experiments were run using an n-propyl amine ?olar bonded phase (C~romosorb LC-9) liquid chromatographic column in both the normal and reversed phase mode. Results confirm that the mechanism of separation in the normal phase is due mainly-to a charge transfer interaction between the lone pair• electrons on the stationary phase nitrogen and the rr electron cloud of the solute PNAs-. Elution order seems to depend upon a combination of rr energy, and type of ring condensation of the solute. Plots of log I •versus number of aromatic carbons for catacondensed PNAs suggest that while the specific interaction is different than that seen in silica chromatography. the overall adsorption effect is comparable. In the reversed 'phase there may be two types of separation mechanisms: 1) a pure partitioning effect in highly polar mobile phases (methanol/water), or 2) a mixture of liquid-solid adsorption and liquid-liquid partition in less polar solvent systems (acetonitrile/water).
