title: Determination of Sulfoxaflor in Animal Origin Foods Using Dispersive Solid-Phase Extraction and Multiplug Filtration Cleanup Method Based on Multiwalled Carbon Nanotubes by Ultraperformance Liquid Chromatography/Tandem Mass Spectrometry.
abstract: In the present study, a rapid analytical method was developed to determine the residue of sulfoxaflor in milk, pork, eggs, porcine liver, porcine kidney, porcine fat, and chicken. The dispersive solid-phase extraction (d-SPE) and multiplug filtration cleanup (m-PFC) based on multiwalled carbon nanotubes (MWCNTs) were compared for sulfoxaflor in the above matrix and then detected by ultraperformance liquid chromatography coupled with tandem mass spectrometry. The analyte was eluted within 5 min using a Waters Acquity UHPLC HSS T3 column under ESI(+) conditions. The limits of detection were 1 μg kg(-1) for all of the matrices. Good linearities of sulfoxaflor were obtained in the range of 1-100 μg L(-1), and the correlation coefficients (R(2)) were higher than 0.9988 in all matrices. The average recoveries of the target compound were between 75.5% and 114.9%, and the intraday and interday relative standard deviation values were <14%. Both methods have purification ability. While considering the cost of analysis and the applicability of the method, d-SPE was selected to purify the samples in the present study. The method was successfully used to analyze the residue of sulfoxaflor in foods of animal origin.
