摘要： A novel and efficient sample pretreatment procedure using magnetic particles was exploited for the determi-nation of multi-pesticide residues in aquatic products. The magnetic adsorbent was prepared using divinyl benzene and N-vinyl pyrrolidone as functional monomers modified on the Fe3O4 @SiO2. The obtained magnetic adsorbent, octadecylsilane sorbents, and graphitized carbon black were employed as effective adsorbents to remove matrix interferences in aquatic products, and their dosages were optimized. Satisfactory levels of ac-curacy and precision were procured under optimum conditions. The method limits of quantification ranged from 0.1 to 2.0 mu g/kg. The analytical accuracy of the developed method for the analysis of multi-pesticide residues in freshwater and seafood products was validated. It was found to be suitable for the analysis of multi-pesticide residues in different types of aquatic products. Additionally, the method was successfully applied for the anal-ysis of pesticide residues in fish samples obtained from aquaculture plants located in Zhejiang Province, China. The detected concentrations of pesticides ranged from 0.14 to 0.95 mu g/kg. In general, this method shows promising application prospects for the rapid determination of multi-pesticide residues in aquatic products.
