Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard was proposed by the Ministry of Natural Resources of the People's Republic of China This standard is under the jurisdiction of the Marine Environmental Protection Subcommittee of the National Marine Standardization Technical Committee (SAC/TC283/SC1). This standard is mainly drafted by. Zhejiang Marine Fisheries Research Institute, Zhejiang Ocean Monitoring and Forecasting Center. The main drafters of this standard. Guo Yuanming, Zhang Shuai, Li Tiejun, Zhang Xiaojun, Yan Zhongyu, Fang Yi, Sun Xiumei, Chen Xuechang, Mei Guangming, Li Peipei, Song Wei. Determination of hexabromocyclododecane in marine sediments High performance liquid chromatography-tandem mass spectrometry

1 Scope

This standard specifies the method for the determination of HBCD in marine sediments by high performance liquid chromatography-tandem mass spectrometry. Method, sample storage, operation steps and calculation of results. This standard applies to the determination of α-HBCD, β-HBCD and γ-HBCD in marine sediments of ocean, offshore, nearshore and estuary.

2 Normative references

The following documents are indispensable for the application of this document. For dated references, only the dated version applies to this article. Pieces. For undated references, the latest edition (including all amendments) applies to this document. GB/T 6682 Analytical laboratory water specifications and test methods GB 17378.2 Marine monitoring specification Part 2. Data processing and analysis quality control GB 17378.3-2007 Marine monitoring specification Part 3. Sample collection, storage and transport

3 Principle of the method

Hexabromocyclododecane in marine sediments is extracted with n-hexane, concentrated by rotary evaporation, purified by silica gel solid phase extraction column, and dried with nitrogen. Alcohol constant volume, high performance liquid chromatography column separation, elution with methanol, acetonitrile and water as mobile phase, high performance liquid chromatography-tandem mass spectrometry The contents of α-HBCD, β-HBCD and γ-HBCD were determined and quantified by internal standard method.
