Analysis of Chloro- and Nitro-Anilines and Benzenes in Soils by Headspace Solid-Phase Microextraction GC-ECD

Quantitative analysis by headspace solid-phase microextraction (HS-SPME) of spiked samples containing twenty chloro and nitro benzenes and analines in model soil matrices was possible when the calibration was performed with the same matrix. The response increased with addition of water to the soil samples, increased soil/headspace surface area and usage of polycrylate rather than polydimethylsyloxane as fibre coating material in the analysis of polar compounds. However, matrix effects, largely depending on the organic carbon content of the soil, were so significant that a standard addition and internal standard is complicated by the missing linearity of the calibration curves when approaching zero and the fact that analytes spiked into the soil matrix can not be assumed to behaveas those present beforehand.
