摘要:
A novel method for determining PAHs in river samples has been developed based on ultrasound-assisted solidified floating organic drop microextraction. The effect of several factors, such as volume of extracting solvent, volume of aqueous sample, sample temperature and extraction time, were evaluated and optimized. Best enrichment efficiency was obtained under the following experimental conditions: 60 mu L of 1-undecanol added into a 30 mL sample solution at 40 degrees C, and then extracted for 10 min in an ultrasonic bath. It showed a good performance for determining the PAHs in river samples and will be a promising method for the reliable determination of PAHs at a very low level in river.
