Evaluation of chromatographic and spectroscopic methods for the analysis of petroleum-derived compounds in the environment

Coupling spectroscopic and chromatographic techniques for evaluation of the depositional history of hydrocarbons in a subtropical estuary

“…Spectroscopic and chromatographic techniques can be used together to evaluate hydrocarbon inputs to estuarine systems (Morel et al, 1991). Recently, gas chromatography coupled to mass spectrometry (GCeMS), together with visible and near-infrared (VIS-NIR) spectroscopy, have been used in combination with various multivariate techniques to determine total PAHs in contaminated soils (e.g.…”

Determination of petroleum hydrocarbons and polycyclic aromatic hydrocarbons in sludge from wastewater treatment basins

“…The analysis of saturated hydrocarbons, PAHs at the trace level in complex mixtures such as sludge is a challenge for the analytical chemist, who has to select, adapt and develop the appropriate methods for sampling, storage, extraction, cleanup and isolation, and sophisticated techniques are needed for identification and quantification. Many authors [3][4][5][6][7][8][9][10] have described methods for trace analyses and discussed problems associated with performing them. Sludge acts as a trap for petroleum-derived compounds originating from the different sources, and is often regarded as one of the worst environmental matrices to extract as it can contain a large variety of pollutants as well as the analytes of interest.…”

“…5,6 An ultrasonic extraction procedure has also enjoyed much success for the extraction of PAHs from sediments as it combines effectiveness with simplicity and speed, but information regarding sonication extraction of PAHs from sludge is still limited. 3 Many workers 2,4,7 have found that different methods give complementary information for the analysis of petroleumderived compounds in the environment. Analytical methods for petroleum pollution studies are of two basic types: spectroscopic and chromatographic methods.…”

“…However, a general feature of these spectroscopic methods is that a clean-up procedure must be carried out preliminarily with great care to avoid contamination. 7 In recent years, capillary gas chromatography with flame ionization detector (GC-FID) has been widely used in petroleum analyses and its application to the proposed task is quite easy. HPLC screening with fluorescence detection has been employed to screen petroleum-related aromatic compounds in sediments and sludges.…”
