In this research, an effervescence-assisted β-cyclodextrin/attapulgite composite (β-CD/ATP) for the in-syringe dispersive solid-phase extraction (EAIS-DSPE) of pyrethroids in environmental samples was developed for the first time. A syringe was used to conduct the extraction procedure and a small amount of β-CD/ATP was dispersed into the solution with the release of carbon dioxide when the effervescent...
A simple, easy-to-use, efficient and environmentally friendly method has been developed for the simultaneous analysis of nine pirethroid pesticides in water samples by the combination of hollow fibre-based liquid-phase microextraction (HF-LPME) and gas chromatography–mass spectrometry (GC/MS). For the developed method, nine pirethroid pesticides (esbiothrin, prallethrin, bifenthrin, tetramethrin,...
A novel method was developed for the determination of eight pyrethroids in water samples by liquid–liquid microextraction based on solidification of floating organic droplets followed by gas chromatography with electron capture detection. The type and volume of the extraction solvents, extraction time, sample solution temperature, stirring rate and ionic strength were studied and optimized. Under...
Stir bar sorptive extraction (SBSE) was applied to the enrichment of pyrethroids in water samples. Analysis was done by retention time-locked GC/MS in selected ion-monitoring (SIM) mode using trans-permethrin-d 6 as internal standard. Thermal desorption (TD) was performed in a classical split/splitless inlet equipped with a flip-top sealing system and in a dedicated thermal desorption unit...
