Abstract
In this work, novel magnetic hypercrosslinked polymers (Fe3O4@BDPF-HCPs) were fabricated by the crosslinking of 1,1′-bis(diphenylphosphino)ferrocene (BDPF) monomer with different external crosslinkers via Friedel-Crafts reaction, followed by modification with Fe3O4 nanoparticles. The Fe3O4@BDPF-HCP-1 was used as a magnetic solid-phase extraction adsorbent to enrich some chlorophenols (CPs) from environmental water, peach beverage and honey samples prior to high performance liquid chromatography analysis. Under the optimum conditions, the target CPs exhibited good linearity with determination coefficient r2 > 0.994. The detection limits of the method (S/N = 3) were 0.03–0.08 ng mL−1 for water, 0.08–0.20 ng mL−1 for peach beverage and 0.3–1.0 ng g−1 for honey sample. The recoveries of CPs in the spiked water, peach beverage, and honey samples were in the range of 80.0 %-112.2 %, 89.0 %-112.2 % and 87.9 %-118.4 %, respectively. The results revealed that the Fe3O4@BDPF-HCP-1 based method can be served as a promising alternative for detection CPs in complex matrix samples.
