Abstract

In this study, a deep eutectic solvent as the acceptor phase was applied in three-phase hollow fiber liquid-phase microextraction for the microextraction of two pyrethroids (permethrin as well as deltamethrin) from environmental water samples prior to HPLC–UV. A deep eutectic solvent was synthesized of tetrabutylammonium bromide–decanoic acid (in a ratio of 1:2) as an acceptor phase and 1-decanol was applied as a supported liquid membrane. Some main variables affecting the extraction recoveries, comprising the types/contents of extraction solvent and acceptor phase, stirring speed, sample phase pH and extraction time, were checked and optimized. Under optimal conditions, the detection limits and limits of quantitation determined were 0.09–0.12 and 0.29–0.39 μgl−1 for deltamethrin and permethrin, respectively. The enrichment factors were 627 and 613, while the relative standard deviations (n = 5) were 4.8 and 5.7%, for deltamethrin and permethrin, respectively. The created technique was assessed as satisfactory to ascertain the two pyrethroid poisons (permethrin and deltamethrin) in environmental water samples. © 2022 John Wiley & Sons Ltd.
