电厂水汽中痕量氯离子在线监测技术分析与探讨

Analysis and Discussion about On-line Monitoring Technology of Trace Chloride Ion in Power Plant Water-Steam

电厂水汽中痕量氯离子的常用检测方法是离子色谱法(IC),流动注射法(FIA)和连续动态法(SFA)结合离子交换富集技术也可实现电厂水汽中痕量氯离子的检测。全面分析了3种方法各自的特点,深入探讨并提出了实现电厂水汽中痕量氯离子工业在线监测的可行性方案。

Ion chromatography （IC） is the common frequently-used detection method of water-steam at power plants, Ion exchange concentration method combined by Flow Injection Analysis （FIA） or Continous Flow Analysis （CFA） also can realize the same detection purpose. The three methods＇ characteristics were analysed comprehensively, the feasible approach for the industrial on-line monitoring technology of trace chloride ion in the water-steam at power plants was raised.
