Abstract

Background and aims: Conventional methods for determination of volatile organic pollutants in the air are based on solvent extraction. Solid-phase microextraction (SPME) has been popular as an environmentally friendly technique to extract a very wide range of analytes. SPME fibers have some drawbacks that can be overcome by the use of sol-gel nanosorbents. Therefore the aim of this study has been to evaluate a nano fiber for sampling and determination of Carbon tetrachloride in air. Methods: In this study, a novel multi-walled carbon nanotube fiber based on sol-gel technique was synthesized and the effects of several factors during sampling and determination of Carbon tetrachloride were evaluated and finally compared with Carboxen/Polydimethylsiloxane (CAR/PDMS) as a commercial fiber. Results: Results showed that the proposed fiber under optimal conditions demonstrated better performances in lower level of both temperature and relative humidity. The efficient temperature for thermal desorption was 280 ° C. The desorption times were obtained at 3 min. The relative standard deviation (RSD) for repeatability ranged between 4 to 4. 3% for reproducibility ranged between 3. 2 to 4. 5%. In comparative studies to CAR/PDMS, the results were acceptable. Conclusion: Solid-phase microextraction with synthesized nano fiber is a simple, sensitive and applied method that can use successfully for determination of Carbon tetrachloride in the air.
