A Study on Separation of Benzoic Acid and Its Derivatives by Anion Exchange Chromatography

[摘要] The anion exchange separation of a number of benzoic acid and its derivatives has been studied in various concentrations of NiCl2-methanol solvent medium. The volume distribution coefficients with Amberlite CG-400, Cl- form have been measured in these medium. Several synthetic mixtures of organic acids were separated quantitatively by elution with a suitable concentration of NiCl2-MeOH solution suggested by the distribution data. The concentration of organic acids were determined by UV spectrophotometry.
