Method for detecting content of three types of brominated flame retardants including tetrabromobisphenol a, decabromodiphenyl ether and hexabromocyclododecane in aquatic products

Abstract

The invention provides a method for detecting the content of tetrabromobisphenol A, decabromodiphenyl ether and hexabromocyclododecane brominated flame retardants in an aquatic product. The method is characterized by comprising the following steps that the content of the tetrabromobisphenol A, decabromodiphenyl ether and hexabromocyclododecane brominated flame retardants in the aquatic product is measured by establishing accelerated solvent extraction-fast liquid chromatography-tandem mass spectrometry, an aquatic product sample needing to be detected is separated through a C18 chromatographic column, gradient elution is conducted by taking water and methyl alcohol as mobile phases, detection is conducted in a mass spectrum multi-reaction monitoring mode, the matrix standard is corrected, quantitative determination is conducted through an external standard method, and confirmation is conducted. The detection method has the advantages that operation is easy and convenient, and detection is fast and accurate; by establishing the method for simultaneously detecting the tetrabromobisphenol A, decabromodiphenyl ether and hexabromocyclododecane brominated flame retardants in the aquatic product, physical health and life safety of consumers are guaranteed, a great practical significance is achieved for promoting sustainable and healthy development of aquatic product processing industry, and a beneficial technical reserve is provided for a food industry supervision department and a detection mechanism.

Description

technical field [0001] The invention relates to the field of food safety detection, in particular to a method for detecting the contents of three types of brominated flame retardants including tetrabromobisphenol A, decabromodiphenyl ether and hexabromocyclododecane in aquatic products. Background technique [0002] As an important member of the food family, aquatic products are becoming one of the first-choice foods for consumers at home and abroad due to their advantages of low fat, high protein, rich nutrition, and delicious taste. At present, the per capita consumption of aquatic products among Chinese residents is at the core of non-staple food consumption status. At the same time, aquatic products are also important export goods in my country, contributing an important force to foreign exchange earnings through export. Therefore, the quality and safety of aquatic products is of great significance to protect people's health and life safety and promote foreign trade of ...

Problems solved by technology

[0004] At present, the main difficulties in the detection and analysis of polybrominated diphenyl ethers (Polybrominated diphenyl ethers, PBDEs), tetrabromobisphenol A (Tetrabromobisphenol A, TBBP-A) and hexabromocyclododecane (HBCDs) include: ESI ionization pairs The specificity of polybrominated diphenyl ether analysis is weak, and it is more susceptible to the interference of complex matrix, which makes it unable to meet the requirements of sample determination

And because some aquatic products are high in oil, the original pretreatment method needs a lot of time
