为贯彻《中华人民共和国环境保护法》和《中华人民共和国水污染防治法》，保护环境，保障人体健康，规范水中挥发性卤代烃的测定方法，制定本标准。
本标准规定了测定水和废水中挥发性卤代烃的顶空气相色谱法。本标准适用于地表水、地下水、饮用水、海水、工业废水和生活污水中挥发性卤代烃的测定。具体组分包括1,1-二氯乙烯、二氯甲烷、反式-1,2-二氯乙烯、氯丁二烯、顺式-1,2-二氯乙烯、三氯甲烷、四氯化碳、1,2-二氯乙烷、三氯乙烯、一溴二氯甲烷、四氯乙烯、二溴一氯甲烷、三溴甲烷、六氯丁二烯等14种。
其他挥发性卤代烃通过验证后，也可以使用本方法进行测定。
本标准是对《水质 挥发性卤代烃的测定 顶空气相色谱法》（GB 17130-1997）的修订。本标准shou次发布于1997年，本次为第yi次修订。自本标准实施之日起，《水质 挥发性卤代烃的测定 顶空气相色谱法》（GB/T 17130-1997）废止。

This standard is formulated to implement the Environmental Protection Law of the People's Republic of China and the Law of the People's Republic of China on the Prevention and Control of Water Pollution, protect the environment, safeguard human health, and standardize the determination method of volatile halogenated hydrocarbons in water.
This standard specifies headspace gas chromatography for the determination of volatile halogenated hydrocarbons in water and wastewater. This standard is applicable to the determination of volatile halogenated hydrocarbons in surface water, groundwater, drinking water, seawater, industrial wastewater and domestic sewage. The specific components include 14 kinds, including 1,1-dichloroethylene, dichloromethane, trans-1,2-dichloroethylene, chloroprene, cis-1,2-dichloroethylene, trichloromethane, carbon tetrachloride, 1,2-dichloroethane, trichloroethylene, monobromodichloromethane, tetrachloroethylene, dibromodichloromethane, tribromomethane and hexachlorobutadiene.
This method can also be used to determine other volatile halogenated hydrocarbons after verification.
This standard is a revision of Water Quality - Determination of Volatile Halogenated Hydrocarbons - Top Air Chromatography (GB 17130-1997). This standard was issued for the first time in 1997, and this is the yi revision. Water quality - Determination of volatile halogenated hydrocarbons - Top air chromatography (GB/T 17130-1997) is abolished from the date of implementation of this standard.
