基于非洛地平在碱性条件下对鲁米诺-K3Fe(CN)6化学发光体系具有很强的增敏作用,结合流动注射技术,建立了直接测定非洛地平的流动注射-化学发光新方法。方法的线性范围为6.0×10-9~3.0×10-6g/mL,检出限为2.1×10-9g/mL,对浓度为1.0×10-7g/mL非洛地平平行测定11次,其相对标准偏差为2.3%,方法已成功应用于片剂中非洛地平含量的测定。 Based on the strong sensitizing effect of felodipine to luminol-K3Fe (CN) 6 chemiluminescence system under basic condition, a new flow injection-chemiluminescence method was established for the determination of felodipine directly by flow injection technique . The linear range of the method was 6.0 × 10-9 ~ 3.0 × 10-6g / mL, with the detection limit of 2.1 × 10-9g / mL. The method was applied to determine felodipine in a concentration of 1.0 × 10-7g / mL for 11 times. The relative standard deviation was 2.3%. The method has been successfully applied to the determination of felodipine in tablets.
