摘要：
A flow-injection analysis (FIA) with a chemiluminescence detection method was developed for the determination of ornidazole based on the inhibition intensity of chemiluminescence from the luminol-ferricyanide system. Under the condition of 1.0 x 10(-3) mol/L luminol and 5.0 x 10(-6) mol/L potassium ferricyanide, the response to the concentration of ornidazole is linear from 0.2 mug ml(-1) to 10 mug ml(-1), and a detection limit of 0.05 mug ml(-1) can be obtained. This method has been successfully applied to the determination of ornidazole in pharmaceutical preparations.
