Determination of polycyclic aromatic hydrocarbons in soil samples using flotation-assisted homogeneous liquid-liquid microextraction.
Hosseini MH, Rezaee M, Mashayekhi HA, Akbarian S, Mizani F, Pourjavid MR. Hosseini MH, et al. J Chromatogr A. 2012 Nov 23;1265:52-6. doi: 10.1016/j.chroma.2012.09.099. Epub 2012 Oct 3. J Chromatogr A. 2012. PMID: 23084825
The filtrate was added into the home-made extraction cell contained mixture of 1.0 mL methanol (homogenous solvent) and 150.0 muL toluene (extraction solvent). Using N(2) flotation, the dispersed extraction solvent was transferred to the surface of the mixture and was coll …

Homogeneous liquid-liquid microextraction via flotation assistance for rapid and efficient determination of polycyclic aromatic hydrocarbons in water samples.
Hosseini MH, Rezaee M, Akbarian S, Mizani F, Pourjavid MR, Arabieh M. Hosseini MH, et al. Anal Chim Acta. 2013 Jan 31;762:54-60. doi: 10.1016/j.aca.2012.10.030. Epub 2012 Oct 24. Anal Chim Acta. 2013. PMID: 23327945
Using optimized variables in the extraction process, for all target PAHs, the detection limits, the precisions and the linearity of the method were found in the range of 14-41 mug L(-1), 3.7-10.3% (RSD, n=3) and 50-1000 mug L(-1), respectively. The proposed method has been …
