Embodiment 1

[0027] The gas chromatography-mass spectrometry method for the determination of phenolic compounds in surface water includes the following parts:

[0028] (1) Sample collection and protection

[0029] The water sample collection container is made of borosilicate glass container or brown glass reagent bottle. The glassware and filter device must be cleaned through the following steps: the glassware and filter device must be cleaned with 1mol / L NaOH solution, then rinsed with distilled water, and finally washed with dichloro For methane washing, a stainless steel water collector is used to collect surface water samples 30cm away from the water surface, and the used bottle is washed 2-3 times with the water samples to be tested before sampling. Sampling is free of headspace and air bubbles. After the water sample is collected, use 4mol / L hydrochloric acid to adjust the pH to 3-4. After the water sample is collected, it should be analyzed as soon as possible. If it cannot be anal...

Abstract

The invention discloses a GC-MS (gas chromatography-mass spectrum) measuring method of phenolic compounds in surface water, and belongs to the technical field of organic pollutants in water environment. The method is characterized in that in the water sample filtering, solid-phase extraction, purification and concentration processes, an ion monitoring GC-MS method is used for measurement; an internal standard method is used for quantification. The measuring method has the advantages that the detection on four kinds of phenolic compounds including octyl phenol, nonyl phenol, bisphenol A and diethylstilbestrol in the surface water has higher sensitivity, accuracy and precision; the measuring method hopefully becomes a new detection standard.

Description

technical field [0001] The invention relates to the technical field of organic pollutants in water environment, in particular to a gas chromatography-mass spectrometry method for determining phenolic compounds in surface water. Background technique [0002] Phenolic compounds are aromatic hydroxyl compounds, the hydroxyl group is connected to the carbon on the benzene ring. According to the number and position of the hydroxyl group and chloride radical on the benzene ring, the common phenols are: phenol, 4-nitrophenol, 3-methyl Base phenol, 2,4-dichlorophenol, 2,4,6-trichlorophenol, pentachlorophenol, etc. In natural water, phenolic compounds are generally not detected, but water sources polluted by industrial wastewater such as coking, gas production, petroleum refining, wood preservation, papermaking and petrochemicals may contain such substances. These phenolic compounds are generally not very toxic, but they often have a foul smell, especially phenol, which can form chl...
