Przeprowadzone badania miały na celu zbadanie wpływu pięciu czynników na stopień ekstrakcji zanieczyszczeń ropopochodnych z gleby z wykorzystaniem aparatu Soxhleta. W celu określenia optymalnej kombinacji tych czynników: liczby cykli na godzinę, czasu ekstrakcji, rodzaju rozpuszczalnika, ilości dodanego środka suszącego oraz ilości dodanej wody, wykorzystano projektowanie doświadczeń metodą Taguchi. Metoda ta uwzględniała pięć zmiennych (na czterech poziomach każdy), w postaci tablicy ortogonalnej L’16. Optymalne warunki ekstrakcji otrzymano dla danych wartości: 50,0 ml chlorku metylenu, czas ekstrakcji 2 godziny, 7 cykli, 1,0 ml wody na 5,0 g próby oraz 1,5 g siarczanu sodu na 5 g próby. Przedstawiona metoda pozwoliła na wyekstrahowanie ponad 90 % oleju napędowego wprowadzonego do matrycy modelowej. Procedura ta okazała się niezawodna i powinna być stosowana do monitorowania środowiska.

This study investigated the influence of five factors on the degree of extraction of a petroleum pollutant from a soil matrix using a Soxhlet apparatus. In order to determine the optimal combination of the five factors, that is, the number of cycles per hour, extraction time, solvent type, the amount of drying agent, and the amount of water added, a Taguchi experimental design was used: five variables (with four levels each) in an L’16 orthogonal array. Optimum extraction conditions were found to be as follows: 50.0 mL of dichloromethane, 2 h extraction time, 7 cycles, 1.0 mL of water added/5.0 g of soil, and 1.5 g of sodium sulfate/5.0 g of sample. Using the presented method, more than 90% of the diesel fuel introduced into the model matrix was extracted. This indicates that the procedure is reliable and should be applied for environmental monitoring.
