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.

Análise do potencial de lixiviação do inseticida sulfoxaflor em solos

“…Trata-se de um princípio ativo novo, desenvolvido e comercializado pela empresa Dow Agrosciences a partir de 2007 (ZE-WAIN et al, 2013), e que já é um dos inseticidas mais usados nas culturas de arroz e trigo (TIAN et al, 2016). No Brasil, foi registrado no fim de 2018, gerando, em pouco tempo, a aprovação de nove marcas comerciais, a saber: Closer, Closer SC, Exor, Exor SC, Expedition, Haffor, Sortic, Verter, Verter SC, todos da referida empresa.…”

“…Ademais, possui potencial de bioacumulação na cadeia alimentar, sendo capaz de afetar, desta forma, a saúde humana (CHEN et al, 2016;TIAN et al, 2016), apesar de ser rapidamente biodegradado no solo. A preocupação é tanta que têm sido desenvolvidos novos métodos de detecção dos resíduos deste composto em alimentos variados como leite, carnes, ovos, hortaliças, dentre outros (XU et al, 2012;DO et al, 2013;KIM et al, 2016;TIAN et al, 2016;CHUANG et al, 2017;CUI et al, 2018;ZHANG et al, 2019).…”

Determination of Ochratoxin A contamination in grapes, processed grape products and animal-derived products using ultra-performance liquid chromatography-tandem mass spectroscopy system

“…Because of their simplicity, high efficiency, and cost-effectiveness, QuEChERS procedures have been applied to the analysis of mycotoxins in barley 23 , rice 24 , and animal feed 25 . Furthermore, QuEChERS methods are flexible, as the optimization of their pretreatment processes allows for the extraction of target compounds from complex matrices including foods of animal origin 26 . In addition, an ultra-performance liquid chromatography (UPLC) system coupled to a Xevo TQ-S triple quadrupole mass spectrometer serves as a powerful tool for the determination of trace levels of pesticides 27 and mycotoxins 28 from various matrices.…”

Performance comparison of dispersive solid-phase extraction and multiplug filtration cleanup methods for the determination of tefuryltrione in plant and environmental samples using UHPLC-MS/MS

“…The d‐SPE‐based QuEChERS method has numerous advantages over traditional SPE, including simplified operation, more economical process time, reduced cost, reduced consumption of organic solvents and greater facilitation of high recoveries, and high‐throughput screening. At present, the d‐SPE‐based QuEChERS method has gained great popularity among researchers for analyzing pesticide residues in fruits , vegetables , cereals , and other matrices . In addition, there arose another novel cleanup method, the multiplug filtration cleanup (m‐PFC) method, which is based on multiwalled carbon nanotubes (MWCNTs), and is effective in removing interferences .…”
