Determination of Polycyclic Aromatic Hydrocarbons in Water by Solid-Phase Microextraction and Liquid Chromatography

Off-line solid-phase extraction procedure for the determination of polycyclic aromatic hydrocarbons from aqueous matrices

“…Detection limits obtained by direct injection of the PAHs standard mixture and calculated with a signal-to-noise of three are between 0.05 and 4 ng. These findings are similar with other research (Chen 2004).…”

“…However, to avoid the adsorption of PAHs on sample containers or connection tubing, an organic solvent (Tfouni et al 2007) or a surfactant should be added before extraction (Ballesteros-Gomez and Rubio 2009;Pino et al 2002;Hung et al 2007). More recently, solid-phase microextraction (SPME) coupled to liquid chromatography (LC) has been used for determination of PAHs in water (Chen 2004). This process is significantly simpler than conventional techniques, thereby reducing analyte loss during extraction.…”

Determination of 1-Hydroxypyrene in Human Urine by Acid Hydrolysis Coupled to Solid-Phase Microextraction and Semi-microcolumn Liquid Chromatography

“…Our past studies indicated that organic sodium chloroacetate can increase the SPME efficiency for an aqueous PAHs' pretreatment. 18 In the present work, we tried to test inorganic and organic salts with ionic strengths of 0.01 -1.0 M. Furthermore, a salting-out test was performed using sodium chloroacetate and sodium acetate, and an organic salts buffer system for SPME was developed. The effect of the ionic strength on the detection of 1-OHP by SPME was checked by comparing fluorescence signals when salt was added to the sample, and when salt was not added to the sample.…”

“…16 The SPME method has subsequently been applied to detect trace organic micro-pollutants, such as volatile organic compounds (VOCs), PAHs and biological samples. [17][18][19] Moreover, when SPME is used for biological samples, it needs a pre-hydrolysis process. Acid hydrolysis is a rapid hydrolysis method used for biological samples, which have been effectively applied for α-cellulose, benzo[a]pyrene tetrol, and DNA-adduct pretreatments in past studies.…”

A Chemical Synthesis of Benzo[a]pyrene Hapten and Its Application in a Streptavidin-Horseradish Peroxidase-Based Enzyme-Linked Immunological Analysis

“…BaP is usually found in exhaust gas produced by the incomplete combustion of fuels, in all smoke resulting from the combustion of organic material and in charbroiled food [6][7][8]. BaP can enter into water bodies mainly via atmospheric fallout, municipal/industrial effluents, urban runoff, and oil spillage [9,10]; it is emitted to the atmosphere from different sources, including industrial processes, combustion of fossils and fuels, and irrational application of pesticide [11].…”
