Abstract

In this paper a simple and efficient technique based on a special format of dispersive liquid–liquid microextraction for extraction/preconcentration of benzene, ethyl benzene, toluene, and xylene isomers (BTEX) from JUICEs has been developed. The extraction method was performed in a narrow-bore tube containing the sample. The extract was then injected into a gas chromatography instrument and quantified against standard solutions. The effect of parameters influencing extraction, such as type and volume of disperser and extraction solvents, sample volume, pH, and ionic strength of the sample solution were evaluated and optimized. Under optimized conditions, the proposed technique showed a linear calibration curve between 6 to 700 mg.L-1 with a correlation coefficient of 0.96, relative standard deviation less than 4.5%, and recoveries between 96.2 to 101.0%. Limit of detection and limit of quantification were calculated to be 1.5-2.2 and 5.0-7.3 mg.L-1, respectively. Enrichment factors were in the range 31-173 folds. Finally in order to evaluate the applicability of the suggested method, it was successfully applied for the analysis of these compounds in a few fruit JUICEs.
