A novel method was developed for the determination of two endocrine-disrupting chemicals, bisphenol A and 4-nonylphenol, in vegetable oil by dispersive liquid-liquid microextraction followed by ultra high performance liquid chromatography with tandem mass spectrometry. Using a magnetic liquid as the microextraction solvent, several key parameters were optimized, including the type and volume of the magnetic liquid, extraction time, amount of dispersant, and the type of reverse extractant. The detection limits for bisphenol A and 4-nonylphenol were 0.1 and 0.06 μg/kg, respectively. The recoveries were 70.4-112.3%, and the relative standard deviations were less than 4.2%. The method is simple for the extraction of bisphenol A and 4-nonylphenol from vegetable oil and suitable for routine analysis.
建立了一种分散液液微萃取-超高效液相色谱-串联质谱法测定植物油中两种环境内分泌干扰物双酚 A 和 4-壬基酚的新方法。以磁性液体为微萃取溶剂，优化了多个关键参数，包括磁性液体的种类和体积、萃取时间、分散剂用量和反萃取剂的种类。双酚 A 和 4-壬基酚的检测限分别为 0.1 和 0.06μg/kg。回收率为 70.4%-112.3%，相对标准偏差小于 4.2%。该方法简单、快速，适用于植物油中双酚 A 和 4-壬基酚的常规分析。
