【Abstract】 A method for the determination of polycyclic aromatic hydrocarbons in soil was established which was extracted by soxhlet’s extraction and solid phase extraction and determined by HPLC using ultraviolet detector. The recoveries by this method were between 82. 7%~96. 2% and the relative standard deviation was less than 10 percent.更多还原
