摘要:
AbstractA 8% cross‐linked sulfonated polystyrene cation exchanger in the hydrogen or sodium form was used as stationary phase for the chromatography of aspirin, salicylic acid and acetic acid. The eluent is 0.02 M mineral acids or their sodium salts in aqueous ethanol. Phosphoric acid, nitric acid or sulfuric acid added in aqueous ethanol eluent made successful separation of aspirin, salicylic acid and acetic acid on hydrogen form cation exchange
