| 摘 要： | 建立了吹扫捕集与气相色谱联用技术结合电子捕获检测器分析水体中多种挥发性卤代烃的方法.定量测定了淮安市自来水、古黄河水、运河、内运河及池塘水中的挥发性卤代烃并进行了对比.结果表明,自来水中主要含有氯仿、三氯乙烯、二溴一氯甲烷等,而自来水水源古黄河水中这三种卤代烃的含量极低.运河和内运河中四氯化碳的含量偏高,而且含有少量四氯乙烯.池塘水与古黄河水水质相近.

| Abstract: | In this paper establishing one method with PAT-GC/ECD to analyze 6 kinds of volatile halohydrocarbons (VHCs), determinating them in tap water, in old Huang He River water, in Canal water, in Internal Canal water and in lake water quantitatively and comparing the VHCs and their content in them. It is shown in the result that CHCl_(3,) C_2HCl_3 and CHBr_2Cl is the great VHCs in tap water and their concentration in its source water is very low compared with that in it. The concentration of CCl_4 in Canal water and in Internal Canal water is higher and a few C_2Cl_4 is detected. The kinds and concentration of VHCs in Lake water is similar to those in old Huang He River water. |
