RISLiquid Phase Microextraction
Abstract :The development of faster, simpler, inexpensive and more environmentally-friendly sample-preparation techniques is an impo-rtant issue in chemical analysis.
Recent research trends involve miniaturization ...
Determination of Aromatic Amines Using Solid-Phase Microextraction Based on an Ionic Liquid-Mediated Sol–Gel Technique
A headspace solid-phase microextraction (HS-SPME) method was developed for isolation of monocyclic aromatic amines from water samples followed by gas chromatography–flame ionization detector (GC–FID). In this work, the ...
Determination of furan in food samples using two solid phase microextraction fibers based on sol–gel technique with gas chromatography–flame ionisation detector
The headspace solid-phase microextraction (HS-SPME) method with two different coatings synthesized
by sol–gel technology [such as poly(ethylene glycol) (PEG) and PEG reinforced with multi-walled carbon
nanotubes ...
Comparative study of the sol–gel based solid phase microextraction fibers in extraction of naphthalene, fluorene, anthracene and phenanthrene from saffron samples extractants
Abstract We are introducing a method for the determination
of some polycyclic aromatic hydrocarbons in aqueous
saffron sample by direct immersion solid phase microextraction
(SPME) and gas chromatography. ...
A novel solid-phase microextraction using coated fiber based sol–gel technique using poly(ethylene glycol) grafted multi-walled carbon nanotubes for determination of benzene, toluene, ethylbenzene and o-xylene in water samples with gas chromatography-flam
In this study, poly(ethylene glycol) (PEG) grafted onto multi-walled carbon nanotubes (PEG-g-MWCNTs)
were synthesized by the covalent functionalization of MWCNTs with hydroxyl-terminated PEG chains. For
the ...

Multiwalled carbon nanotubes/polypyrrole/SiO2 composite prepared by electrodeposition technique as a new solid phase microextraction sorbent for preconcentrationon of BTEX
BTEX is the collective name of benzene, toluene, ethylbenzene, and the xylene isomers (p, m,
and o-xylenes), all being harmful volatile organic compounds (VOCs). Human exposure to these
compounds can have ...
