Scope

Main technical content: Establishing detection methods for cefalexin C in antibiotic fermentation residues (remaining culture medium residues after fermentation) and organic fertilizer base materials, soil, crops, and water and air after harmless treatment. The technical principles and processing procedures are as follows: (1) Cefalexin C in the antibiotic fermentation residue samples is extracted with water, purified by a solid-phase extraction column, and determined by a high-performance liquid chromatography-ultraviolet detector using an external standard quantification method; (2) Soil and crop samples are first ground and crushed, then extracted with water, purified by a solid-phase extraction column, and detected by an ultra-high performance liquid chromatography-tandem mass spectrometer using an external standard quantification method; (3) Water samples are directly purified by a solid-phase extraction column and detected by an ultra-high performance liquid chromatography-tandem mass spectrometer using an external standard quantification method; (4) Air samples are collected using an absorption bottle with water as the absorption solution, centrifuged and filtered, and then separated by ultra-high performance liquid chromatography and detected by a tandem mass spectrometer using an external standard quantification method. The cefalexin C concentration in antibiotic fermentation residues and organic fertilizer base materials should be 0.05 mg/kg; in soil, 10 μg/kg; in crops, 10 μg/kg; in water, 0.1 μg/L; and in air, 0.02 μg/m3.
