| 摘 要： | 在磷酸介质中，痕量苯胺对过碘酸钾氧化罗丹明6G使其荧光猝灭具有抑制作用，据此建立了动力学荧光法测定痕量苯胺的新方法。方法的线性范围为0.010～0.183 μg·mL-1，检出限为7.2 ng·mL-1。本法灵敏度高、线性范围宽，用于测定酚醛塑料管材和水样中苯胺的含量，回收率在100%～104% 之间，结果令人满意。

| Abstract: | An inhibitory kinetic fluorimetric method is reported for the determination of trace aniline. The proposed method is based on the inhibitory effect of aniline on the reaction of potassium periodate oxidation of rhodamine 6G in phosphoric acid medium. The detection limit is 7.2 ng x mL(-1), the linear range of the determination is 0.010-0.183 microg x mL(-1). This method has been applied to the determination of trace aniline in phenolic tubes and water samples with satisfactory results. |
