摘  要：
[Objective]The research aimed to detect the content of carbofuran in water by high performance liquid chromatography(HPLC) with post-column derivation and fluorimetric detector.[Method]Water samples were enriched and purified with ENVI-18 extraction column.Taken methanol-water as mobile phase,the samples were separated by chromatographic column.After the reaction of post-column derivatization,the content of carbofuran was detected by fluorescence detector.[Result]The results showed that the obtained correlation coefficient was >0.999 at the test range of 50-1 000 μg/L.The minimum detection limit was 0.036 μg/L.The average recovery rates of the pesticides ranged from 91.5% to 97.3%.[Conclusion]The proposed method was fast and sensitive,and could be used for monitoring pesticide residues in normal water.
