| 摘 要： | 在压水堆核电站蒸发器的泄漏率试验时，为了测定水中的痕量硼，先使水中的硼酸在酸性条件下与氢氟酸作用，生成四氮硼酸，再让四氟硼酸与亚甲基蓝作用生成氟此使可获知水中的浓度，从而进一步得到蒸发器的泄漏率。

| Abstract: | In nuclear power plant of pressurized water reactor it is necessary to determine the concentration of trace boron in water for testing the leakage rate of the steam generators. First hydroloric acid is added to the water sample in acidic medium, which reacts with boric acid in the water to form tetrafluoroboric acid. Then tetrafluoroboric acid reacts with methylene blue and the tetrafluoroboric acid-methylene blue complex is formed. The complex is extracted by 1,2-bichloroethane and by measuring absorbance at 668nm the boron concentration in the water sample can be determined.Finally the leakage rates of the steam generators can be determined. |
