摘要: Magnetic ordered porous carbon (MOPC–ZSM-5) was synthesized using zeolite ZSM-5 as a template and sucrose source. It used magnetic solid-phase extraction adsorbent for the of four neonicotinoid insecticides (acetamiprid, imidacloprid, thiacloprid thiamethoxam) from river water peanut milk samples prior to high performance liquid chromatography–ultraviolet detection. The calibration curves in showed linearity 1.0 200.0 ng mL−1 thiamethoxam, 0.5 acetamiprid. For samples, observed range 6.0–1000.0 thiacloprid, 3.0–1000.0 acetamiprid, respectively. developed method has been successfully applied determination satisfactory result obtained.
