本标准规定了测定环境空气中挥发性卤代烃的活性炭吸附-二硫化碳解吸/气相色谱法。
本标准适用于环境空气中氯苯、苄基氯、1,1-二氯乙烷、1,2-二氯乙烷、反式-1,2-二氯乙烯、顺式-1,2-二氯乙烯、1,2-二氯丙烷、1,2-二氯苯、1,3-二氯苯、1,4-二氯苯、1,1,1-三氯乙烷、1,1,2-三氯乙烷、三氯乙烯、三氯甲烷、三溴甲烷、1-溴-2-氯乙烷、1,2,3-三氯丙烷、1,1,2,2-四氯乙烷、四氯乙烯、四氯化碳、六氯乙烷等21 种挥发性卤代烃的测定。若通过验证，本标准也可适用于其他挥发性卤代烃的测定。

Scope

This standard specifies the activated carbon adsorption-carbon disulfide desorption/gas chromatography method for the determination of volatile halogenated hydrocarbons in ambient air. This standard applies to chlorobenzene, benzyl chloride, 1,1-dichloroethane, 1,2-dichloroethane, trans-1,2-dichloroethylene, cis-1,2- Dichloroethylene, 1,2-dichloropropane, 1,2-dichlorobenzene, 1,3-dichlorobenzene, 1,4-dichlorobenzene, 1,1,1-trichloroethane, 1,1 ,2-trichloroethane, trichloroethylene, chloroform, bromoform, 1-bromo-2-chloroethane, 1,2,3-trichloropropane, 1,1,2,2-tetrachloroethane Determination of 21 volatile halogenated hydrocarbons such as alkane, tetrachlorethylene, carbon tetrachloride, and hexachloroethane. If verified, this standard can also be applied to the determination of other volatile halogenated hydrocarbons. When the sampling volume is 10L, the detection limit of this standard method is 0.03~10 μg/m, and the lower limit of determination is 0.12~40 μg/m. See Appendix A for details.
