基于磁性多壁碳纳米管的磁性固相萃取-超高效液相色谱-串联质谱法测定农产品中22种真菌毒素OA北大核心CSTPCD
Magnetic Multi-Walled Carbon Nanotubes Nanomaterials as Magnetic Solid Phase Extraction Adsorbents for Simultaneous Determination of Multiple Mycotoxins in Agricultural Products by Ultra-High Performance Liquid Chromatography-Tandem Mass Spectrometry
以磁性多壁碳纳米管(Fe3O4-MWCNTs)为吸附剂,建立了简单、快速和高效的磁性固相萃取方法,结合超高效液相色谱-串联质谱实现了对农产品中 22 种真菌毒素的同时检测.将Fe3O4 纳米颗粒引入MWCNTs中制备Fe3O4-MWCNTs作为吸附剂,不仅可以提高多种目标真菌毒素的富集效率,还可通过外磁场进行分离,有效缩短了样品前处理时间.对影响磁性固相萃取前处理效率的提取溶液、吸附剂类型、吸附剂用量和洗脱溶液类型进行了优化.在最佳前处理条件下,…查看全部>>
A simple,rapid and efficient magnetic solid-phase extraction(MSPE)method was established by employing magnetic multi-walled carbon nanotubes(Fe3O4-MWCNTs)as adsorbents.And further,by coupling with ultra-high performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS),an accurate quantitative approach for analysis of 22 kinds of mycotoxins in agricultural products was developed.With Fe3O4-MWCNTs as MSPE adsorbents,the enrichment efficiency of vario…查看全部>>
