Microwave-assisted sequential extraction of polyclic aromatic hydrocarbons and potentially toxic elements from urban environmental solids
A method has been developed for the sequential extraction and determination of polycyclic aromatic hydrocarbons (PAHs) and potentially toxic elements (PTEs) from urban substrates using microwave-assisted micellar extraction, the BCR sequential extraction procedure (BCR-SEP) and microwave-assisted …

Thermal and chemical analysis of carbonaceous materials: diesel soot and diesel fuel reactor deposits
… and is traditionally obtained via Soxhlet extraction of soot using an organic solvent. Chemical speciation of the SOF was performed using GC-MS analysis. Five solvents (hexane, cyclohexane, toluene, methanol and acetone) were compared with dichloromethane, the most extensively used solvent …

Monitoring of atmospheric polycyclic aromatic hydrocarbons through optimization of analytical techniques
… of disease. Polycyclic aromatic hydrocarbons (PAHs) have been widely used as markers of environmental pollutants in the context of ambient air, indoors, as well as in working environments. Sampling, extraction, sample clean up and analysis constitute the principal stages required for the …
