| Abstract |
A rapid simple procedure was developed to extract residual Benzo-a-pyrene from a single hi-vol filter strip. It involves quantitative dispensing of cyclohexane, 10 minutes of ultrasonication at 78C and a quiescent period of 1 hour. At that time the solvent is ready for chromatography. |
