tom 04

nr 1

In this paper physical, chemical and toxical properties of the polycyclic aromatic hydrocarbons (PAHs) have been described. Different methods for isolation of these compounds from air, water and soil were presented. Various chromatographic methods such as gas chromatography (GC and CGC/MS), high performance liquid chromatography (HPLC) with UV-Vis, diode array and fluorescence detection, thin-layer chromatography (TLC) and supercritical fluid chromatography (SFC) were applied for PAH determination.

The process of the isolation of malathion from water matrix has been optimized from the point of recovery. Solid phase extraction (SPE) columns with different material packings have been used to study the dependence of recovery on adsorbent type, structure and character. Solid membrane EMPORE with C-18 groups has also been used for this investigation. Comparison of extraction efficiency obtained for SPE column and extraction disc has been done.

A new type of stationary phase with specific structural properties and different undersurface structure (monomeric and polymeric) for liquid chromatographic separation has been prepared. This phase was applied for the separation of polycyclic aromatic hydrocarbons (PAHs), particularly those, recommended by the U.S. National Institute of Standards and Technology (NIST) and the U.S. Environmental Protection Agency (EPA). For comparative studies the commonly-used C-18 phase, with monomeric and polymeric structure created on the same batch of silica gel support, was applied. Physico-chemical and chromatographic properties were determined using different instrumental methods (porosimetry, elemental analysis, CP/MAS NMR, liquid chromatography), particularly under hydro-organic conditions.
