Separation of Ferulic Acid Reagent by Powdered Activated Charcoal

Abstract

Abstract: Powdered activated charcoal was used to separate ferulic acid reagent in the solution. The results showed that powdered activated charcoal has high capacity for adsorbing ferulic acid. Its maximum adsorption capacity is 325～340mg/g and it could adsorb all ferulic acid in the solution when the concentration of ferulic acid is lower than 5mg/100ml at pH2.0～9.0. 2.0% of NaOH could desorb almost 100% of the adsorbed ferulic acid, whereas alcohol and ethyl acetate could desorb less than 30% of the adsorbed ferulic acid. The results of TLC showed that ferulic acid separated by powdered activated charcoal from alkali-hydrolyzed sugarcane bagasse has high purity.

Key words: powdered activated charcoal, ferulic acid, separation, TLC(Thin Layer Chromatography)
