Online-SPE high performance liquid chromatography with dual detectors for the determination of carbendazim,sulfonamides and neonicotinoid residues in soil
In this research,seven pesticide residues in soil,including carbendazol,thiacloprid,imidacloprid,sulfamethoxaz,nitenpyram,sulfadiazine and sulphaguanidine,have been concentrated and detected with online solid phase extraction-high performance liquid chromatography( SPE-HPLC) method. Both of online-SPE concentration and parameter determination of HPLC-DAD / FLD have been optimized to get the best experimental conditions: the target compounds in soil samples were extracted by the mixed solution of methyl alco...
