Abstract

Phenol is a toxic environmental pollutant possessing carcinogenic and mutagenic properties. Determination of phenol in soil by certified methods requires long and laborious sample preparation. Solid-phase microextraction (SPME) allows much simpler and faster determination of pollutants in soils. However, method accuracy is limited by the problem of effective matrix effect control. The aim of this study was to develop a rapid and inexpensive method for the quantitative determination of phenol in soil using SPME, gas chromatography-mass spectrometry and standard addition. Extraction temperature 80°C provides the lowest relative standard deviation being 2.1 and 4.6% for aqueous and soil samples, respectively. Soil equilibration time after addition of phenol standard at 80°C should take at least 6 h. The developed method was successfully tested on model and real soil samples having phenol concentrations 0.44 and 0.059 mg/kg, respectively. Coefficients of linear approximation of calibration dependences were higher than 0.97. Method detection limit depends on the affinity of matrix to analyte and is lower than 10 µg/kg.
