Abstract:
Objective To explore the determination of nicotine in cigarettes by fluorescein and fluorimetry-basic possession of bonuses system.Methods Nicotine could interfere with fluorescence energy transfer between fluorimetry-basic possession of bonuses.A new way of energy transfer was established to determinate nicotine according to the fluorescence increment of fluorimetry.Results The linear range was 0.2-7.0 mg/L for the concentration of nicotine.The correlative coefficient was 0.9992.The detection limit was 0.18 mg/L.The recovery rates were 99.0 %-105 %,and RSDs were 1.1 %-4.8 % respectively.Conclusion This method is simple,fast,accurate and sensitive.It can be used to determinate nicotine in cigarettes.
