Objective: To establish a rapid and precise continuous flow-injection chemiluminescence (CL) method to determine ribavirin. Methods: The ribavirin could restrain strongly CL reaction of luminol in sodium hydroxide (NaOH) solution with potassium chlorate (KClO3). The different experimental parameters affecting the CL intensity were studied carefully. Results: Under optimum conditions (The concentrations of luminol, KClO3, and NaOH were at 0.1 mmol/L, 0.5μmol/L, and 0.2 mol/L, respectively), the linear range of the working curves was 0.01-7.00μg/ml with a detection limit of 0.004μg/ml. Conclusion: The method is simple, rapid and sensitive, and successfully applied to the determination of ribavirin in pharmaceutical preparations and biological fluids.
