氯化橡胶生产过程中需排放大量含CCl_4的污水,因此必须进行控制分析。使用气相色谱法分离污水中的微量CCl_4,用选择性好,灵敏度高的电子捕获检测器测定含量,可获得满意的结果。图1抓化橡胶粉化塔和洗涤水色谱图一、实验条件选择氯化橡胶生产污水,除含有大量水份和微量CCI、外,还含有其他未知杂质。
Chlorinated rubber production process requires the discharge of a large amount of wastewater containing CCl_4, it must be controlled analysis. Separation of trace amounts of CCl_4 in wastewater by gas chromatography and satisfactory results were obtained with a good selectivity and high sensitivity electron capture detector. Figure 1 Grasping rubber powder tower and washing water chromatograms First, the experimental conditions Select chlorinated rubber production of sewage, in addition to containing a lot of water and trace CCI, but also contains other unknown impurities.
