酸性介质下,KMnO4氧化阿魏酸产生化学发光,乙二醛对该体系有增敏作用。结合流动注射技术,建立了测定阿魏酸的流动注射化学发光新方法。该方法线性范围为1.0×10-7～2.0×10-5mol/L,检出限为1.0×10-8mol/L,对1.0×10-6mol/L的阿魏酸平行测定11次,相对标准偏差为2.8%。该法用于太太美容口服液中阿魏酸的测定,结果令人满意。 Under acidic medium, KMnO4 oxidized ferulic acid to produce chemiluminescence, and glyoxal sensitized the system. Combined with flow injection technique, a new flow-injection chemiluminescence method for the determination of ferulic acid was established. The linear range of this method was 1.0 × 10-7 ~ 2.0 × 10-5mol / L, the detection limit was 1.0 × 10-8mol / L, and the method was parallel to 11 × 10-6mol / L ferulic acid for 11 times. The relative standard The deviation is 2.8%. The method was applied to the determination of ferulic acid in Mrs. Beauty oral liquid and the results were satisfactory.
