为排查流通环节鱼用麻醉剂的潜在风险,本研究建立了水中丁香酚残留的测定方法。本方法以乙酸乙酯作为提取剂,使用气相色谱-串联质谱仪对丁香酚进行定性和定量测定。结果显示,在1.00~200.00μg/L的浓度范围内,标准曲线方程为y=14.65 x-7.23,相关系数r为0.999 4,线性拟合良好。加标浓度在5.00~100.00μg/L范围内回收率范围为98.6%~104%,相对标准偏差范围为2.46%~5.48%。方法检测限和定量限分别为0.21和0.68μg/L。本方法准确、简单、快捷,能够满足鱼类产品流通环节水中丁香酚残留的测定。
In order to investigate the potential risk of narcotics in circulation, this study established a method for the determination of eugenol residues in water. This method uses ethyl acetate as the extractant, using gas chromatography-tandem mass spectrometry qualitative and quantitative determination of eugenol. The results showed that the standard curve equation was y = 14.65 x-7.23 and the correlation coefficient r was 0.999 4 in the concentration range of 1.00 ~ 200.00μg / L with a good linear fit. The recoveries ranged from 98.6% to 104% with the spiked concentrations ranging from 5.00 to 100.00 μg / L with relative standard deviations ranging from 2.46% to 5.48%. The detection limits and the limits of quantification were 0.21 and 0.68 μg / L, respectively. The method is accurate, simple and fast, and can satisfy the determination of eugenol residues in fish in the circulation of fish products.
