| description | The invention relates to the technical field of detection of nitrofuran metabolites, and particularly discloses a method for detecting nitrofuran metabolites in aquatic products. The detection method comprises the following steps: sample pretreatment: taking a water product, adding a standard sample, adding an internal standard working solution and hydrochloric acid, uniformly mixing, adding a derivatization reagent, carrying out a derivatization reaction, sequentially adding ethyl acetate and a neutral strong electrolyte after the reaction is completed, oscillating, and carrying out sample pretreatment; centrifuging, collecting an organic phase, blow-drying with inert gas, redissolving, and filtering to obtain on-machine to-be-detected liquid; the derivatization reagent is a benzaldehyde substance with carboxyl. The detection method of the nitrofuran metabolites can be used for detecting the nitrofuran metabolites in aquatic products, and has the advantages of high accuracy, good sensitivity and simple and c |
