Abstract

The invention relates to a method for quantitatively detecting 2, 4-dichlorophenol in water, belonging to the field of analysis and detection of a compound. The invention provides a method for detecting 2, 4-dichlorophen in water through a head space solid phase microextraction-gas chromatography. The extracting head of the solid phase microextraction has the effect of gathering volatilizing components and can detect trace 2, 4-dichlorophen in water. The method can be used as a standard method for detecting the concentration of 2, 4-dichlorophen in water, the pretreatment is simple and rapid, and only needs heating and extracting for 30 minutes, no solvent is needed, the method is safe and environment-friendly, the dosage of the sample is less, the method has good linear adding standard recovery, and the detection sensitivity can reach 6.54mu g / L.

Description

technical field

[0001] The invention relates to the quantitative detection of 2,4-dichlorophenol in water. The method combines headspace solid-phase microextraction and gas chromatography detection technology to quickly and accurately quantitatively detect 2,4-dichlorophenol, which belongs to compound analysis detection field. Background technique

[0002] 2,4-Dichlorophenol (2,4-DCP) is a toxic and refractory organic pollutant, which is replaced by chlorine atoms at the 2 and 4 positions on the benzene ring of phenol produced. Over the years, it has entered the environment through human activities such as waste incineration, uncontrolled use of wood preservatives, pesticides, fungicides, herbicides, and pulp bleaching; at the same time, as a solvent, lubricant Agents and synthetic waste are released into the environment.

[0003] 2,4-Dichlorophenol has the three effects of "teratogenic, carcinogenic and mutagenic". It can accumulate in the body and has strong biological ...
