Embodiment 1

[0020] Embodiment 1: Determination of triclosan content in tap water. The tap water analyzed in the test was collected by our laboratory, and the analysis results showed that the tap water did not contain triclosan. In order to evaluate the accuracy of the established method, add 1.0ugL -1 Triclosan, the recovery rate of triclosan was determined to be 83.6%. The results proved that the water quality of tap water had little effect on the liquid phase microextraction of triclosan. In order to evaluate the precision of method measurement, add 1.0ug L in tap water -1 For triclosan, 5 parallel determinations were performed with a relative standard deviation of 6.9%.

Embodiment 2

[0021] Example 2: Determination of the content of triclosan in the water sample of Wohushan Reservoir in Jinan, the analysis result shows that the water sample does not contain triclosan. Crouching Tiger Mountain Reservoir Water in Triclosan 1.0ug L -1 Concentration level, the recovery rate was 114.1%.

Abstract

The invention discloses a rapid analysis method of a triclosan in the environment water sample. The rapid analysis method solves the problem that the method is in want of quickly and accurately examining the triclosan in the environment water sample at present is solved. The rapid analysis method has the advantages of briefness and convenience, quickness, noxious solvent, accurate analysis, short preliminary treatment time of the sample, etc. The amount of the noxious solvent is utilized less. The methods are: 1) a derivatization reagent is used for a home position derivation. 2) A phase micro-extraction of the spatial textile fiber liquid is used for extracting. 3) Finally, a gas chromatograph is used for measuring and the examination result is obtained.

Description

technical field [0001] The invention relates to a method for detecting organic pollutants, in particular to a rapid analysis method for accurately analyzing triclosan in environmental water samples by using hollow fiber liquid-phase microextraction-chromatography-mass coupling. Background technique [0002] Triclosan, also known as 2,4,4'-trichloro-2'-hydroxydiphenyl ether, is a common pollutant in water. It is not only a common antibacterial drug, but also used as a personal care product (such as: Shampoo, soap, deodorant) preservative. Triclosan itself has low toxicity, so it is largely ignored in conventional wastewater treatment, however studies have shown that under certain conditions, for example when hypochlorite is present or due to photochemical reactions, triclosan can are converted into more toxic and persistent pollutants such as chlorophenols. Therefore, it is very necessary to develop an analytical method for rapid monitoring of triclosan in environmental wat...
