在酸性介质下,KMnO4可以氧化2-硝基酚产生化学发光,乙二醛对该发光体系有增敏作用。结合流动注射技术,建立了测定2-硝基酚的流动注射化学发光新方法。该方法线性范围为8.0×10-10～5.0×10-6 mol/L,检出限为1.0×10-11mol/L,对1.0×10-7 mol/L的2-硝基酚平行测定11次,相对标准偏差为2.4%。该法已用于实际水样中2-硝基酚的测定。 Under acidic medium, KMnO4 can oxidize 2-nitrophenol to produce chemiluminescence, and glyoxal sensitizes the luminescent system. A new flow-injection chemiluminescence method was developed for the determination of 2-nitrophenol by flow injection technique. The linear range of the method was 8.0 × 10-10 ~ 5.0 × 10-6 mol / L, the detection limit was 1.0 × 10-11mol / L, and the method of parallel determination of 2-nitrophenol with 1.0 × 10-7 mol / L Times, the relative standard deviation of 2.4%. The method has been used for the determination of 2-nitrophenol in actual water samples.
