摘要：

The direct supercritical-fluid extraction (SFE) of polycyclic aromatic hydrocarbons (PAHs) from aqueous solutions was studied. The influence of supercritical fluid pressure and temperature on analyte recovery and kinetics of the direct SFE of PAH mixtures was investigated. A method for PAH determination in water based on their direct supercritical-fluid extraction and on off-line solventless coupling with GC was developed. A detection limit for the developed method ppt level was achieved. The water sample was 10 mt The total extracted volume was analyzed by GC-FID or GC-MS.
