Method for detecting halogenated benzamide through solid phase extraction-liquid chromatography-tandem mass spectrometry

The invention discloses a method for detecting halogenated benzamide through solid phase extraction-liquid chromatography-tandem mass spectrometry, and belongs to the field of drinking water micropollutant detection. The method comprises the following steps: sequentially performing solid-phase extraction enrichment and nitrogen blowing concentration on a target compound, and finally quantitatively determining the content of 2-chlorobenzamide, 2, 4-dichlorobenzamide, 2, 6-dichlorobenzamide, 2-bromobenzamide, 2-iodobenzamide, 3, 4-dichlorobenzamide, 3, 4-dichlorobenzamide, 3, 4-dichlorobenzamide, 3, 4-dichlorobenzamide and 3, 4-dichlorobenzamide in the drinking water by adopting a multi-reaction monitoring mode of liquid chromatography-tandem mass spectrometry. The concentration of the 2-chloro-4-hydroxybenzamide, the concentration of the 5-bromine-2-hydroxybenzamide, the concentration of the 2-chloro-4-hydroxybenzamide and the concentration of the 5-bromine-2-hydroxybenzamide are different. According to the me
