- 摘要：用过滤、XAD树胎吸附和阴离子树脂吸附等方法将引滦水中的天然有机物分离为悬浮态、憎水化合物、腐殖酸类化合物、非腐殖酸类阴离子化合物和其它亲水化合物等。分别对不同形态有机物进行氯化处理, 测定了产物中的挥发性卤代烃。结果表明, 引滦水中天然有机物的主要气化产物是氯仿和一溴二氯甲烷, 此外还生成少量二溴一氯甲烷。悬浮态有机物和溶解态腐殖酸是生成氯仿的最重要母体。一溴二氯甲烷和二溴一氯甲烷则大多来源于溶解态腐殖酸。
- Abstract：Total organic carbon(TOC)in water from Yinluan Channel was frac-tionated into five fractions of suspended, hydrophobic compounds, humic subs-tances, anions, and other hydrophillic compounds.The individual fractionswere chlorinated separately and the volatile halogenated organics generatedduring the chlorination were measured by GC.The results showed that theprimary products were chloroform and bromodichloromethane.Dibromochlo-romethane was detected as well.The suspended organics and the dissolvedhumic substances were the most important precursors of chloroform whilealmost all the other halogenated organics were generated from dissolved humic substances alone.
- Key words：halogenated organic DOC TOC humic substances frac-tionation.
