a new method for extracting and measuring methoxyfenozide using nd/pan-k10 spe using high performance liquid chromatography

A sensitive, economical, and miniaturized self-assembly needle tip nanocomposite polyaniline-k10 solid-phase microextraction (ndt/pan-k10-spne) coupled with high-performance liquid chromatography uv detection was developed for rapid extraction removal and determination of methoxyfenozide in environmental water samples. the ndt/pan-k10-spe cartridge, assembled by packing 2.0 mg of pan-k10 as sorbent into a needle tip, showed high adsorption capacity for methoxyfenozide owing to the large surface area and unique structure of pan-k10. the factors that affected the extraction efficiency of pt-g-spe, including sample volume, ph, sorbent amount, washing solvent and eluent solvent, were optimized. good linearity for methoxyfenozide was obtained in a range of 0/01–100 µg ml−1 with the correlation coefficient of (r2) = 0.999. the recoveries of the methoxyfenozide at three spiked levels ranged from 84.72% to 100.03% with the relative standard deviations (rsd) of 3.78%. it is also noteworthy that the applied method is economical and has a good linear range, reproducibility, and high sensitivity.
