Determination of 6PAEs in Sediment by Ultrasound Extraction-HPLC
A rapid method for the determination of 6 kinds of PAEs in river sediment by ultrasonic extraction and high-performance liquid chromatography was proposed.The results showed that the six PAE components were linearly good from 0 to 5 µg/mL concentration range(r＞0.999).When the sampling amount was 5.00 g,the detec-tion limit was 0.0129～0.0387 mg/kg.For determining the standard material(RMU00la),the results are within the standard value range;the recovery rate of the actual sample spike is between 83.3％and 107.8％.It is concluded that ultrasonic extraction with HPLC is suitable for rapid determination of 6 PAEs in sediment.
