Polyvinylimidazole/sol-gel composite as a novel solid-phase microextraction coating for the determination of halogenated benzenes from aqueous solutions

English Abstract

A polyvinylimidazole/sol–gel composite is proposed as a novel solid-phase microextraction fiber to extract five halobenzenes from the headspace of aqueous solutions in combination with GC–MS. The prepared fiber was characterized by scanning electron microscopy and FTIR spectroscopy. The obtained results showed that porous polyvinylimidazole/sol–gel composite was chemically deposited on fused silica fiber. The effect of important extraction parameters, including extraction temperature, extraction time, and salt content were investigated. The optimum conditions were extraction temperature 25°C, extraction time 20 min, and salt concentration 30 (w/v%). Detection limits and relative standard deviations of the developed method for halogenated benzenes were below 0.1 pg/mL and 15%, respectively. Repeatability of the proposed method, explained by relative standard deviation, varied between 5.48 and 9.15% (n = 5). The limits of detection (S/N = 3) ranged between 0.01 and 0.10 ng/L using GC–MS with selected ion monitoring mode. For real sample analysis, three types of water samples with different matrices (ground, surface and tap water) were studied. The optimized procedure was applied to extraction and method validation of halogenated benzenes in spiked water samples.
