| Abstract: | The separation of 1,4,5,8-naphthalenetetracarboxylic acid from impurities coexisted and quantitative analysis by area normalization method were examined by using reverse liquid chromatography (RLC) method. The detection wavelength, sample preparation and the optimization of mobile phase constitution were discussed. As a result, the present compound can be determined by HPLC with C18column, methanol and pH4.5 sodium dihydrogenphosphate buffer solution as eluting agent and ultraviolet detection wavelength at 238nm. |
