A magnetic nanoparticles(MNPs)is synthesized and applied to extraction and enrichment of 4 pyrethroid insecticides residues(tefluthrin,bifenthrin,cyfluthrin,deltamethrin)from Xiangjiang River.The parameters influencing the extraction efficiency of pyrethroid insecticides such as the amount of MNPs,desorption sovlvent and time,type and volume of desorption solvent are optimized.Under optimized condition,the method is successfully applied to the extraction of pyrethroid insecticides from… CONTINUE READING
