교반막대 추출법과 GC-MS/MS를 이용한 수중의 합성 향물질류 분석

A highly sensitive analytical method based on stir bar sorptive extraction (SBSE) technique and gas chromatography/tandem mass spectrometry (GC-MS/MS) has been developed, allowing the simultaneous multi-analyte determination of 11 syntheticfragrances (SFs) in water samples. The stir bar coated with polydimethylsiloxane (PDMS) was added to 40 mL of water sample atpH 3 and stirred at 1,100 rpm for 120 min. Other SBSE parameters (salt effect and presence of organic solvent) were optimised. The method shows good linearity (coefficients > 0.990) and reproducibility (RSD < 10.9%). The extraction efficiencies were above83% for all the compounds. The limits of detections (LOD) and limits of quantification (LOQ) were 2.1~4.1 ng/L and 6.6~12.9ng/L, respectively. The developed method offers the ability to detect 11 SFs at ultra-low concentration levels with only 40 mL ofsample volume. Matrix effects in tap water, river water, wastewater treatment plant (WWTP) final effluent water and seawaterwere investigated and it was shown that the method is suitable for the analysis of trace level of 11 SFs. The method developedin the present study has the advantage of being rapid, simple, high-sensitive and both user and environmentally friendly.
