Abstract
The recoveries of extraction solvent, clean-up solvent and real sample were surveyed to establish the analytical method of PAHs(poly aromatic hydrocarbons) in liquid samples. The average recoveries of extraction solvent were surveyed 70¡102% in the selected solvents. The dichloromethane and n-hexane as non-polar solvents, and dichloromethane:acetone, n-hexane:acetone, cyclohexane :acetone, dichloromethane:methanol(1:1) and dichloromethane:methanol (10:1) as combined solvents were examined the extraction recoveries over 80%. Also, in the silicagel column process, the dichloromethane:pentane(2:3), 10% dichloromethane:n-hexane and 40% dichloromethane:n-hexane as elution solvents were represented over 87% recoveries. The analytical method in liquid sample, which extracted with dichloromethane:methanol(10:1) and eluted with 10% dichloromethane:n-hexane selected to get the highest recovery.
