Alumina-based Fiber for Solid Phase Microextraction of Alcohols from Gaseous Samples

Alumina-based fiber for solid phase microextraction of alcohols from gaseous samples.

On the basis of the affinity of alumina towards hydroxyl functional groups, a solid phase microextraction (SPME) fiber was constructed using alumina powder and poly(vinyl chloride) (PVC). Different compositions were tested and alumina:PVC (97:3) was selected as an optimun composition. A piece of silver wire was used as fiber support. The fiber producing was simple and could be completed in a fe...

HCl- Etched Steel Fiber for Determination of Phthalates in Water Samples by Solid-Phase Microextraction

In the present work, a stainless steel wire was etched by hydrochloric acid during a chemical etching process. The obtained black layer on the surface of the fiber was used as sorbent for extraction of trace amount of phthalates in the aqueous samples by solid phase microextraction. New fiber efficiency was investigated using a home-made solid-phase microextraction (SPME) device and gas chr...

Ordered Nanoporous Carbon Based Solid-Phase Microextraction for the Analysis of Nitroaromatic Compounds in Aqueous Samples

In this paper, the possibility of using a new ordered nanoporous carbon as a new fiber in headspace solid phase microextraction (HS-SPME) to determine of mononitrotoluenes (MNTs) in waste water is demonstrated. The structural order and textural properties of the ordered nanoporous carbon were studied by X Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) images and nitrogen adsorpti...

Ordered nanoporous carbon (CMK-3) coated fiber for solid-phase microextraction of benzene and chlorobenzenes in water samples

Nanoporous carbons (CMK-3) were prepared and have been used as a fiber coating for headspace solid phase microextraction (HS-SPME). The prepared materials were characterized by Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD) and N2 adsorption/desorption isotherms. The efficiency of the fiber was evaluated using a gas chromatography (GC) system for the extraction of benzene (B) and c...
