Determination of Polycyclic Aromatic Hydrocarbons in Olive and Refined Pomace Olive Oils using HPLC/FLD
ABSTRACT: In this study, an analytical method is developed to determine 15 polycyclic aromatic hydrocarbons (PAHs) in olive and refined pomace olive oils using HPLC coupled with a fluorescence detector. The standardised method of ultrasound-assisted solvent extraction consisted of liquid–liquid extraction with organic solvent and purification on C18 and Florisil bonded-phase cartridges was modi...
متن کامل9. Organic Geochemistry of Surface Sediments of the Sulu Trench/philippines
During cruise SO 58 of the FRG research vessel Sonne in 1988, surface sediments were collected from the deep waters of the Sulu Trench (Philippines) for organic geochemical investigations. The purpose of geochemical analyses of surface sediments is to obtain information on the nature and origin of gaseous hydrocarbons detected in these sediments and from this information to estimate the hydroca...
متن کاملKinetics of substrate utilization and bacterial growth of crude oil degraded by Pseudomonas aeruginosa
Pollution associated with crude oil (CO) extraction degrades the quality of waters, threatens drinking water sources and may ham air quality. The systems biology approach aims at learning the kinetics of substrate utilization and bacterial growth for a biological process for which very limited knowledge is available. This study uses the Pseudomonas aeruginosa to degrade CO and determines the ki...

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 کاملHydrochemical and isotopic effects associated with petroleum fuel biodegradation pathways in a chalk aquifer.
Hydrochemical data, compound specific carbon isotope analysis and isotopic enrichment trends in dissolved hydrocarbons and residual electron acceptors have been used to deduce BTEX and MTBE degradation pathways in a fractured chalk aquifer. BTEX compounds are mineralised sequentially within specific redox environments, with changes in electron acceptor utilisation being defined by the exhaustio...
