“…Meanwhile, a lot of analytical techniques have been developed to recognize and monitor these PAHs effectively. Among them, gas chromatography (GC) and high performance liquid chromatography (HPLC) techniques are two of the most widely used techniques to analyze PAHs qualitatively and quantitatively http owing to their high precision [3][4][5]. But they are expensive, tedious, time-consuming, and require large amounts of solvents.…”

A new fast and effective analysis method has been developed to simultaneously determine 16 polycyclic aromatic hydrocarbons in reclaimed water samples by ultra-performance convergence chromatography with photodiode array detection and solid-phase extraction. The parameters of ultra-performance convergence chromatography on the separation behaviors and the crucial condition of solid-phase extraction were investigated systematically. Under optimal conditions, the 16 polycyclic aromatic hydrocarbons could be separated within 4 min. The limits of detection and quantification were in the range of 0.4-4 and 1-10 μg/L in water, respectively. This approach has been applied to a real industrial wastewater treatment plant successfully. The results showed that polycyclic aromatic hydrocarbons were dramatically decreased after chemical treatment procedure, and the oxidation procedure was effective to remove trace polycyclic aromatic hydrocarbons.

“…However, there are still three difficulties in the analysis of PAHs: (a) lower volatility of heavy PAHs, (b) the limited use of the column during analysis, and (c) lower sensitivity of flame ionization detector (FID). Due to the high sensitivity of mass spectrometry (MS), gas chromatography-mass spectrometry (GC-MS) [1][2][3][4] has also been applied to PAHs. However, while this method resolves the third problem mentioned above, it increases the cost of analysis.…”

Summary. This paper develops an instrumental analytical approach for detection of fourteen polycyclic aromatic hydrocarbons (PAHs) in edible oil samples using gel permeation chromatography (GPC) and ultra-high performance liquid chromatography (UHPLC) coupled with diode array detector (DAD), and fluorescence detector (FLD). The GPC was used to remove triglycerides from edible oil samples. The extracted samples were then detected using UHPLC-DAD-FLD. In order to obtain good separation and high reproducibility, the UHPLC-DAD-FLD experimental condition was optimized. The PAHs including three groups of isomeric PAHs can be separated completely in 12 min using BEH Shield RP 18 column with a suitable gradient elution program. The mean recoveries were in the range of 73-110% with an acceptable reproducibility (RSD < 10%, n = 3). During real sample analysis, the method can decrease the chance of false positives with both DAD and FLD being used simultaneously. The results indicate that the approach is simple, easy, and acceptably reproducible, thereby showing great potential as a method for detection of fourteen PAHs contained in edible oil samples.
