Liquid Microextraction

A simple microextraction method, magnetic stirring assisted demulsification dispersive liquid–liquid microextraction, for preconcentration of five polycyclic aromatic hydrocarbons (fluorene, phenanthrene, anthracene, fluoranthrene, and pyrene) was investigated prior to analysis by high performance liquid chromatography. In this method, a mixture of extraction solvent and disperser solvent was rapidly injected into sample solution. The magnetic stirrer agitator aided the dispersion of the extraction solvent into the sample solution. After the formation of an emulsion, the demulsifier was added, resulting in the rapid separation of the mixture into two phases. No centrifugation step was required. Several parameters affecting the extraction efficiency of the proposed method were studied, including addition of salt, kind and volume of extraction solvent, volume of demulsifier solvent, and extraction times. Under the optimum conditions, high enrichment factor, low limit of detections (LODs) and good precision were gained. The proposed method was successfully applied to analysis of polycyclic aromatic hydrocarbon residues in grilled pork samples.

Abstract A simple and rapid analytical method for the extraction and quantification of four polycyclic aromatic hydrocarbons in milk sample has been developed using dispersive liquid–liquid microextraction followed by the use of HPLC. Benzo(a)pyrene, benzo(a)anthracene, and benzo(b)fluoranthene were used as model compounds; the milk sample was spiked with these compounds to assess the extraction procedure. Experimental parameters that influence the extraction efficiency, including the nature and volume of the disperser and extraction solvents, pH, and the volume of milk sample, were optimized. Under the optimum extraction conditions (extraction solvent: chloroform, 200 μL; dispersive solvent: acetonitrile, 700 μL; and extraction time 5 s or less), the performance of the proposed method was evaluated. The chromatographic peak area was linear with concentrations in the range of 0.2–10 ng/mL−1 and with correlation coefficients ranging from 0.9968 to 0.9985. The LODs, based on a S/N ratio of 3, ranged from 0.06 to 0.18 ng/mL−1. The RSDs varied from 3.68 to 9.7% (n = 3). The recoveries of these compounds were from 88.38 to 100%. The performance of the present method was evaluated for the determination of polycyclic aromatic hydrocarbons in various types of milk samples.
