“…Multivariate analysis is an important statistical tool that has been used to predict physicochemical properties of petrochemical products from gas chromatography (GC), − Fourier transform infrared spectroscopy (FTIR), − nuclear magnetic resonance (NMR), , and other optical methods. , Chemometric statistical methods were used to analyze fuel degradation, , the mechanism of fire retardants, the relationship between composition and HC emission, particulate matter compositions, solvent extraction of petroleum HCs in sediments, and parameters of smoke emission control . GC and chemometric techniques were used for pattern recognition classification of diesel and jet fuel and in the analysis of specific constituents in fuel as naphthalenes and aromatics in jet fuel, HC in gases, or multicomponents in fuels, − besides sulfur in diesel by FTIR.…”

This report describes innovative methods for sample pretreatment in organic environmental analysis that involve the use of microwave‐assisted techniques. The methods described include: microwave‐assisted extraction (MAE), focused microwave‐assisted Soxhlet extraction (FMASE), microwave‐assisted headspace analysis, microwave‐assisted derivatization (MAD), microwave‐assisted saponification (MAS) and microwave‐assisted decomposition. A brief history of the development of each technique is provided. Reference is made to literature published up to the beginning of 1999.

Microwave‐enhanced solvent extraction is a relatively new approach for the extraction of organic pollutants from solid environmental matrices. This approach uses microwave technology to heat organic solvent in contact with the sample in either a sealed (pressurized) or open (atmospheric) vessel. The major advantage of this approach over conventional extraction procedures, such as Soxhlet extraction, is the speed of the process. As well as the principles of microwave heating, the article also describes the instrumentation required to effect the extraction process. Finally, selected applications of microwave‐enhanced solvent extraction are described. Applications are divided into extraction from solid matrices and extraction from aqueous matrices. The specific analytes covered include the extraction of polycyclic aromatic hydrocarbons (PAHs), hydrocarbons, polychlorinated biphenyls (PCBs), pesticides and phenols from solid matrices; direct extraction of chlorinated benzenes from aqueous matrices; microwave elution of a range of analytes from solid‐phase extraction (SPE) media and, finally, volatile compounds, e.g. benzene, toluene, ethylbenzene and xylenes (BTEX) from aqueous samples. Finally, some recommended operating conditions for the extraction of analytes from solid matrices using pressurized microwave‐assisted extraction (MAE) are provided.
