Ultrasonic extraction of total particulate aromatic hydrocarbons (TpAH) from airborne particles at room temperature
Abstract:
A superior enrichment procedure for the extraction of TpAH from airborne particles collected on glass fiber filter paper is described. The sample is suspended in a solvent and subjected to ultrasonic waves at room temperature with glass powder to adsorb polar coextractives. The TpAH in the filtered extracts are separated from other compounds by high speed liquid chromatography. Sensitivity is in the nanogram range, and the procedure is highly reproducible. Significantly larger amounts of TpAH are recovered than with Soxhlet extraction for 6 to 8 hours, and the percentage of pAH in the extracts is much higher. The entire procedure requires approximately 40 minutes, most of which is waiting time.
