Description:
Petroleum hydrocarbons (PHC) are common soil contaminants. A number of methods have been used to extract PHCs from soil prior to quantification by gas chromatography (GC). These methods often require long extraction times and expensive, specialized equipment. A shaking method was assessed for simple, rapid removal of PHCs from contaminated soils. Shaking spiked and aged contaminated soils for 4 h with acetone:hexane (1:1) at a soil:solvent ratio of 1:30 (g:mL) recovered 74 to 108% of PHC, compared with a Soxhlet extraction, yielding a good correlation (4 h = −93.7 + 0.99 Soxhlet r = 0.99, P 〈 0.001). Preliminary results show that this 4-h procedure has potential for the quick, inexpensive extraction of PHCs from contaminated soils.
