Abstract
Polycyclic aromatic nitrogen heterocycles (PANHs) are present in the environment in broad range of concentrations along with polycyclic aromatic hydrocarbons (PAH) and their derivatives, amino-, nitro-, methyl-, etc. Actual determinable amount of PANHs may vary depending on their fate in environmental samples. Adsorption and/or complexation processes accompanied by volatilization take place especially in soil samples. Successful identification and content determination of PANHs in complex mixtures requires efficient methods of their extraction from environmental samples, suitable preseparation, preconcentration and final analytical determination. Common used extraction methods recommended for isolation of PAHs, their derivatives and analogues may not be suitable for aromatic heterocycles, such as PANHs. The very low value of final amount determined in the complex mixture of may be result of significant difference affinity of extracted pollutant and applicable extraction solvent. Differences in extraction recovery of set of PANHs from soil observed using different extraction solvents is presented in the paper.
