Abstract
A solid-phase extraction method for the quantitation of 16 regulated polycyclic aromatic hydrocarbons (PAHs) was developed and conditions were optimized to meet the recoveries stated in US Environmental Protection Agency Method 550.1. The best elution procedure soaked the extraction cartridge with acetonitrile followed by elution with methylene chloride. Rinsing the sample bottle with acetonitrile and combining the rinse with the sample extract was necessary to achieve the desired recoveries. The average recovery for a mixture of the sixteen regulated PAHs was 83%.
