Objective To determine disodium edetate in Metronidazole and sodium Chloride injection.Methods Thechromato-graphic column was Agilent C18 (150mm×4.6mm,5μm),with acetonitrile∶aqueous tetrabutylammonium phosphate buffer∶water(20∶20∶60)as the mobile phase.The detection wavelength was 254nm and the flow rate was 1.0mL/min.The injection volume was 20μL.Results The calibration curves of disodium edetate were linear in the range from 0.1 to 2.0μg(r=0.9998).The average recovery was 98.11%,with RSD of 1.06%(n=9).Conclusion The method is simple and accurate,sensible and reproducible,which can be used for the quality control of determining disodium edetatein in Tinidazole and soudiun Chloride injection.
