Ultrasonic Wave Extraction and Simultaneous Analysis of Polycyclic Aromatic Hydrocarbons (PAHs) and Phthalic Esters in Soil

摘要

A method was developed for the determination of polycyclic aromatic hydrocarbons (PAHs) and Phthalic Acid Esters (PAEs) in soil sample. Ultrasonic Wave Extraction under airtight circumstance was adopted to extract the analyte in soil sample with n-hexane - acetone (V:V=1:1 ) to be extraction solvent. This method has advantages of high efficiency extraction, short time, convenience and simplicity, which can be popularized in polycyclic aromatic hydrocarbons (PAHs) and Phthalic Acid Esters (PAEs) detection in soil.
