| Abstract: | The chemiluminescence system,luminol-Cu（Ⅱ）-vitamin B2 was discovered.A new method for the determination of vitamin B2 was established by flow injection chemiluminescence.The experimental conditions that affected the chemiluminescence reaction were carefully optimized.The concentration of vitamin B2 was linear related to the chemiluminescence intensity in the range of 2.0×10^-8—2.0×10^-6g/mL.The detection limit was 8×10-9g/mL.The relative standard deviation was 2.3% for the 11 replicate determination of 2.0×10^-7g/mL vitamin B2 solution.The method was applied to the determination of vitamin B2 in pharmaceutical preparation. |
