    An analytical method has been validated for the analysis of hydrocarbons in marine sediment samples. Hydrocarbon extracts were measured by GC-FID and GC-MS-TIC after clean-up and separation process. The proposed protocol is able to measure n-alkanes and PAH in sediment samples at concentration as low as 30 ng/g. preparation – filtration and DNA extraction – for the analysis of sea water samples Höfundar / Authors Eyjólfur Reynisson, Árni Rafn Rúnarsson, Sveinn Haukur Magnússon, Desiree Seehafer, Viggó Þór Marteinsson Skýrsla / Report no. 36‐10 Útgáfudagur / Date: Nóvember File Size: 1MB.

    Pressurized liquid extraction (PLE) for simultaneous extractions of polycyclic aromatic hydrocarbons (PAHs) and alkylated PAHs (alkPAHs) in marine sediments was optimized. The conditions, could be greatly influenced the extraction efficiencies such as extracting solvent, pressure, and temperature, were examined using dry samples spiked PAHs and by: 2.

A shaking extraction method for petroleum hydrocarbons in soil was developed and compared to Soxhlet extraction. Soxhlet extraction is an EPA-approved method for volatile and semivolatile organic contaminants from solid materials, but it has many disadvantages including long extraction periods and potential loss of volatile compounds.

When field-moist soils are used, Cited by: Automated Supercritical Fluid Extraction (SFE), using CO 2, was tested and optimised for routine analysis of hydrocarbons (THC), polychlorinated biphenyls (PCB) and polycyclic aromatic hydrocarbons (PAH) in marine aim of the exercise was to reduce the amount of solvents used and to reduce the manual handling time for each by:   In order to determine PAHs in marine sediment samples by GC/MS(SIM) a new extraction approach of ASE-SFE was evaluated using combined accelerated solvent extraction (ASE, dynamic and static mode) and supercritical fluid extraction (SFE, dynamic mode) without further purification of the sample.

A microwave-assisted solvent extraction (MASE) technique was developed for the quantitative extraction of gasoline- and diesel-range petroleum hydrocarbons (PHs) from soil and marine sediment samples.

The influence of different extracting solvents, extraction temperature and duration of extraction on the recoveries of PHs was evaluated using a two-level Cited by: 4. Polycyclic aromatic hydrocarbons (PAHs) comprise a group of chemical compounds consisting of two or more fused benzene rings.

PAHs exhibit hydrophobicity and low water solubility, while some of their members are toxic substances resistant to degradation. Due to their low levels in environmental matrices, a preconcentration step is usually required for their determination.

The use of a novel micro pressurized liquid extraction (µPLE) method for the isolation of 16 priority pollutant polycyclic aromatic hydrocarbons (PAHs) from various solid samples is explored. The technique employs rapid heating in a single static extraction mode to remove analytes in a matter of seconds from 5–10 mg samples using only µL of by: 1.

The ability of several methods to extract polycyclic aromatic hydrocarbons (PAHs) and other petroleum hydrocarbons from marine sediments was examined. Comparisons of soxhlet and methylene chloride reflux methods gave extraction efficiencies that showed no statistical difference in the return of PAHs; however, the return when using ball-mill tumbling was.
