Summary This standard specifies the method for the determination of halogenated organic compounds in seawater desalination concentrated seawater, mainly for the volatile halogenated hydrocarbons, chlorophenols, chloroacetic acid, trichloroacetaldehyde and organochlorine pesticides produced by the chlorine disinfectant during seawater desalination. This standard is applicable to the determination of volatile halogenated hydrocarbons, chlorophenols, chloroacetic acid, trichloroacetaldehyde and organochlorine pesticides in seawater desalination concentrated seawater, sea inlets and adjacent sea waters. See Appendix A for method detection limits.

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 National Marine Standardization Technical Committee (SAC/TC283). This standard was developed by Tianjin Sea Water Desalination and Comprehensive Utilization Research Institute of Ministry of Natural Resources, Tianjin Marine Environment Monitoring Center Station of State Oceanic Administration, Pony Test Technology Co., Ltd. is responsible for drafting. The main drafters of this standard. Liu Jing, Zeng Xingyu, Zhou Dongxing, Zhao Yunrong, You Jing, Tu Jianbo, Gong Yao, Jiang Hongyou, Pan Xianhui, Hao Jun, Song Wei, Yu Jianwei, Li Xia. Discharge of medium halogenated in seawater desalination concentrated seawater Determination of organic matter by gas chromatography Warning---Personnel using this standard should have practical experience in formal laboratory work. Contact is required during the operation of this standard determination method A large number of organic reagents did not point out all possible safety issues. The user is responsible for taking appropriate safety and health measures to ensure compliance with national standards. The conditions stipulated by the relevant laws and regulations of the country.

1 Scope

This standard specifies the method for the determination of halogenated organics in seawater desalination concentrated seawater, mainly for the introduction of chlorine bactericides in the desalination process Produced volatile halogenated hydrocarbons, chlorophenols, chloroacetic acid, trichloroacetaldehyde and organochlorine pesticides. This standard is applicable to volatile halogenated hydrocarbons, chlorophenols, chloroacetic acid and trichlorohydrin in seawater desalination of concentrated seawater, discharges into the sea and adjacent water bodies. For the determination of acetaldehyde and organochlorine pesticides, see Appendix A for the detection limit of the method.

3 Terms and definitions

The following terms and definitions defined in GB 17378.2 apply to this document. 3.1 Seawater desalination engineering New, expansion, and reconstruction projects for seawater utilization that transform seawater into fresh water through desalination. [GB/T 22413-2008, definition 3.2] 3.2 Concentratedseawater After the seawater is extracted by desalination technology, the seawater is more than doubled.

4 Volatile halogenated hydrocarbons

4.1 Principle The water sample is placed in a sealed headspace bottle and equilibrated at a certain temperature for a certain period of time. The chloroform, carbon tetrachloride, and bromo Chloroform, dibromochloromethane and tribromomethane escape to the upper space and reach dynamic equilibrium in the gas-liquid two-phase. At this time, volatile halogenated hydrocarbons The concentration in the gas phase is directly proportional to its concentration in the liquid phase. The volatile halogenated hydrocarbons in the gas phase were determined by gas chromatography.
