RISSynthesis and application of a novel solid-phase microextraction adsorbent: Hollow fiber supported carbon nanotube reinforced sol–gel for determination of phenobarbital
A novel solid-phase microextraction technique using a hollow fiber-supported sol–gel combined withmulti-walled carbon nanotubes was employed in the determination of phenobarbital in wastewater. In this new technique, a silica-based, organic...
Headspace solid phase microextraction of volatile aromatic hydrocarbons using a steel wire coated with an electrochemicalprepared nanocomposite consisting of polypyrrole, carbon nanotubes, and titanium oxide
We have prepared a new material for solid-phase microextraction (SPME) of volatile aromatic hydrocarbons by electropolymerization of pyrrole, carbon nanotubes, and titanium oxide on the surface of a stainless steel wire. This fiberlike wire was used...
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 effect of the presence of ionic...
