Determination of selected nitropolycyclic aromatic hydrocarbons in water samples.
A new method for the analysis of selected nitropolycyclic aromatic hydrocarbons (NPAHs) at ultra-trace levels in water samples is proposed. Particulate NPAHs were collected on a GC glass fiber filter. Soluble NPAHs were collected on a C18 Empore disk. After simple clean-up and concentration of NPAHs in both phases, the NPAHs were analyzed using HPLC equipped with clean-up, reducer, concentratio...
متن کاملDetermination of Polycyclic Aromatic Hydrocarbons in Ambient Urban Air
Polycyclic aromatic hydrocarbons (PAHS) have been determined in the atmosphere of Isfahan, Iran. Airborne particulate matter was sampled using a high-volume air sampler at roof-top level (~6m). Extraction of PAHS from airborne particulate matter has been performed using SFE system and the relationship between the extraction temperature and the recovery of PAHS</su...

A green and efficient ionic liquid-based ultrasound-assisted in-situ solvent formationmicroextraction (IL-UA-ISFME) in combination with high-performance liquid chromatographyultravioletdetection (HPLC-UV) has been successfully developed for the trace determination offive selected polycyclic aromatic hydrocarbons (PAHs) in environmental water samples. In thismethod, a hydrophobic ionic liquid (1...
متن کاملDetermination of polycyclic aromatic hydrocarbons (PAHs) in river water samples from the Vaal Triangle area in South Africa.
PAHs are fused ring aromatic pollutants some of which are highly carcinogenic to humans and are persistent in the environment. The objective of this study was to develop a suitable extraction method for PAHs from river water samples, identify and quantify the individual compounds. An optimized reverse solid phase extraction (SPE) method was used after conditioning the sorbent to extract and pre...
متن کاملDetermination of Polycyclic Aromatic Hydrocarbons in Biological Samples by Dispersive Liquid-Liquid Microextraction and Gas Chromatography
This work presented determination of some polycyclic aromatic hydrocarbons such as naphthalene, phenanthrene and acenaphthene in biological samples by Dispersive Liquid-Liguid Microextraction (DLLME) and gas chromatography. In this method, the appropriate mixture of extraction solvent (dichloromethane) and disperser solvent (acetone) are injected rapidly into the aqueous sample by syringe. Ther...
