Determination of Polycyclic Aromatic Hydrocarbons in Surface Water by Isotope Dilution Method with Large Volume Injection Zhang Yongtao1 Zhang Li1 Zhang Guiqin2 1Institute of Hydrogeology and Environmental Geology 2School of Foreign Languages Experimental Center of Hydrogeology and Environmental Southwest University Geology Chongqing China Shijiazhuang China zhangguiqin1988@ icpzytws@ Abstract—By improving chromatographic resolution and Mass naphthalene-d8, acenaphthene-d10, the phenanthrene-d10, Spectrometry scanning method, an isotope dilution method Chrysene-d12 as naphthalene, acenaphthene, the phenanthrene, which can detect Naphthalene, Acenaphthene, Phenanthrene and Chrysene during sample pre-treatment. Since analyte and Chrysene in water samples is established. Compared with stable isotope dilution is one to one correspondent and have Liquid-liquid Extraction, double Purification of solid phase similar physicochemical properties and similar behavior during extraction column and Silica Gel Column is more suitable for the process of pre-treatment and chromatographic separation, it large volume injection. Their retention behavior of solid phase extraction and chromatographic behavior have basic consistency fully guarantees the recovery of analyte. Using C18 solid phase because of the Physicochemical properties of analyte and di
