Preparation of an ionic liquid-mediated carbon nanotube-poly(dimethylsiloxane) fiber by sol–gel technique for determination of polycyclic aromatic hydrocarbons in urine samples using head-space solid-phase microextraction coupled with gas chromatography
A novel ‘ionic liquid-mediated multi-walled car- bon nanotube (MWCNT)-poly(dimethylsiloxane) (PDMS)’
hybrid coating was prepared by the covalent functionalization of MWCNTs with hydroxyl-terminated PDMS using the sol– gel technique...
Solid-phase microextraction based sol–gel technique using poly(ethylene glycol) grafted multi-walled carbon nanotubes as extracting phase
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 first ...

Nanopowders of HoBa2Cu3O7-ä have been prepared by a citrate gel modification of the sol–gel technique atdifferent calcination temperatures, using high-purity nitrate salts of Y, Ba and Cu as starting materials and citric acid as complex agent...
A solid phase microextraction coating based on ionic liquid sol–gel technique for determination of benzene, toluene, ethylbenzene and o-xylene in water samples using gas chromatography flame ionization detector
Ionic liquid mediated sol–gel sorbents for head-space solid phase microextraction (HS-SPME) were
developed for the extraction of benzene, toluene, ethylbenzene and o-xylene (BTEX) compounds from
water samples ...
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. ...
Determination of monocyclic aromatic amines using headspace solid-phase microextraction based on sol–gel technique prior to GC
In this research, the headspace solid-phase microextraction (SPME) coupled with GC flame
ionization detector was applied for the determination of some monocyclic aromatic amines
in real water and urine samples. A sol–gel technique...
