In this paper, solid phase extraction (SPE) was used to enrich water samples. The extraction solution was purged and concentrated by nitrogen and then quantitatively determined by gas chromatography. The factors affecting the recovery rate were tested to determine the solid phase extraction column and eluting solvent. Experiments show that the method is simple, rapid, sensitive, low detection limit, less organic reagent consumption, accurate and reliable, and can meet the analysis requirements of trace deltamethrin in surface water.
