High-performance liquid chromatography(HPLC) was used for the determination of EDTA disodium salt remained in viral vaccines.EDTA disodium salt reacts with FeCl3 to form a stable complex,NaFe EDTA,which generate apparent absorption at 257nm wavelength.After isolating other component with C18 column,five grade calibration curves were established by external standard method.The results showed that this a accurate,rapid way and can be used to detect residual EDTA disodium salt in viral vaccines.
