摘要
建立了用气相色谱法测定环境空气中二氯甲烷和二氯乙烷的方法。环境空气中二氯甲烷和二氯乙烷用活性炭吸附,二硫化碳解吸,NNOWAX毛细管柱分离,氢火焰离子化检测器检测。本方法前处理简便,分离度好,分析灵敏度高,满足环境分析要求。
Gas chromatography determination of methylene chloride and dichloroethane in ambient air was established. Methylene chloride and dichloroethane in ambient air used activated carbon adsorption and carbon disulfide desorption, NNOWAX capillary column separation, and hydrogen flame ionization detector. The pretreatment method was simple, good separating degree, analysis of high sensitivity, and satisfied the requirement of environmental analysis.
