In-Depth Information
Organophosphate triesters
Pressurized liquid extraction and solid-phase
extraction followed by gas chromatography-
mass spectrometry
Water as a component of extraction
solvent; low consumption of organic
solvents
[120]
Pesticides, pharmaceutical and personal
care products
Sequential superheated liquid extraction and
gas chromatography-mass spectrometry
Water as extraction solvent; shorter
extraction times; lower extractant volumes
and easier rupture of analyte-matrix
interaction
[121]
Polycyclic Aromatic Hydrocarbons
Static pressurized liquid extractor coupled to
a flow injection and high performance liquid
chromatography with fluorimeter detection
Water as extraction solvent; minimal use of
organic solvents
[122]
Polychlorinated biphenyls
Static subcritical water extraction coupled
with solid-phase microextraction and gas
chromatography with electron capture
detector
Simple and inexpensive apparatus; water as
extraction solvent; no sample drying steps
are required and no organic solvent wastes
are generated;
[123]
Polycyclic Aromatic Hydrocarbons
Static subcritical water extraction with
simultaneous solid-phase extraction and gas
chromatography with flame ionization
detection
Very simple and rapid method; water as
extraction solvent; minimal use of organic
solvents
[124]
Polycyclic Aromatic Hydrocarbons
Ultrasonic micellar extraction and high
performance liquid chromatography with
ultraviolet detection
More rapid than other conventional
extraction methods; not require the use of
potentially hazardous organic solvents;
extracts from sonication can be
chromatographed without subsequent
clean-up steps; analysis time considerably
reduced.
