Solid-Phase Extraction Combined with Dispersive Liquid–Liquid Microextraction for the Simultaneous Determination of Deltamethrin and Permethrin in Honey by Gas Chromatography–Mass Spectrometry

In this study, solid-phase extraction combined with dispersive liquid–liquid microextraction is presented for the simultaneous determination of trace amounts of deltamethrin and permethrin in honey by gas chromatography–mass spectrometry. First, permethrin and deltamethrin were extracted from polluted honey samples by ultrasound-assisted liquid–liquid extraction followed by solid-phase extraction (SPE). Then, the analytes were eluted from the...
