Abstract:To determine the content of nitrite in Tinidazole by ion chromatograph, Dionex IonpacTMAS18 Anion Column (4 mm×250 mm) was used using KOH solution (5 mmol/L) as eluent and the conductance detector. Experimental data showed that a good linearity was obtained at a nitrite concentration range of 0.014~0.443 μg/mL; and an average recovery of 101.1% was obtained. This method is accurate and fast, which can be used for the determination of nitrite in Tinidazole.
Key words:ion chromatography; Tinidazole; nitrite; content determination
