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