摘要
本文提出采用顶空直接进样和毛细管柱气相色谱法检测废水中氯乙烯的方法。该方法使用低毒、不易挥发的N,N-二甲基甲酰胺(N,N-Dimethylformamide,简称DMF)作为溶剂,配置氯乙烯标准曲线母液的吸收液,该方法最低检出限为0.002 mg/L,标准样品的相对标准偏差为1.1%-1.3%,实际水样加标回收率在98%-101%,相对标准偏差与加标回收率均满足国际标准的要求。
A method for the determination of vinyl chloride in wastewater by capillary column gas chromatography was studied in this paper. The method choose N,N-Dimethylformamide as the solvent which is low toxicity,non volatile who is the absorption liquid configuration standard curve of vinyl chloride liquid,the limits of detection was 0.002 mg/L,the RSD of standard sample was 1.1%-1.3%,the recoveries of practical water was 98%-101%. The RSD and recoveries meet the requirements of international standards.
