Abstract

The invention discloses a method for detecting six phthalates in drinking water through liquid chromatography-mass spectrometry, and belongs to the technical field of drinking water detection. The method comprises the following steps: (1) additionally arranging a protection column; (2) measuring conditions and a mode; (3) establishing a standard working curve; (4) detecting to-be-detected drinking water. According to the detection method, a sample is not required to be pretreated and can be directly fed, so that the six phthalates (DMP (Dimethyl Phthalate), DEP (Diethyl Phthalate), DBP (Dibutyl Phthalate), BBP (Benzyl Butyl Phthalate), DEHP (Di 2-Ethyl Hexyl Phthalate) and DNOP (Di N Octyl Phthalate)) in the drinking water are qualitatively and quantitatively analyzed at high speed; the method has the advantages of easiness and convenience in operation, less sampling quantity, low cost, good reproducibility, high stability and the like, is not only suitable for daily environment monitoring and is also suitable for quick screening of pollutants in emergency accidents.

Description

technical field

[0001] The invention relates to a detection method, in particular to a simple and fast qualitative and quantitative detection method for six phthalates in drinking water, belonging to the technical field of drinking water detection. Background technique

[0002] Phthalic acid esters (PAEs) are an important class of endocrine disruptors. Trace amounts of PAEs will be enriched in water, soil, animals and plants, difficult to degrade in the environment, interfere with the endocrine system of the human body, and directly affect the metabolism of the human body. The plasticizer bis(2-ethylhexyl) phthalate Ester (DEHP) is 20 times more toxic than melamine. Studies have shown that plasticizers can also increase the burden on the liver and kidneys, cause chronic damage to the immune system and digestive system, and even lead to liver cancer. In the liquor incident in 2012, the highest detection value of dibutyl phthalate (DBP) in the sample was 1.04mg / kg. With the...
