In this study, the equilibrium dialysis method was used to study the characterization of ferulic acid (FA) adsorption on arabinogalactan (AG). Firstly, the indicators including temperature, pH, and the concentration of FA on the adsorption were investigated by single factor experiments. Then, the Box-Behnken design was used to optimize the adsorption conditions. Finally, the structural characterization of the complex was analyzed by Fourier transform infrared spectroscopy, UV spectroscopy, scanning electron microscopy. The results showed that the optimized conditions of FA adsorption on AG were 20 ℃ at pH 5.02 with 15 mg/mL FA. Under this condition, the adsorption capacities of FA on AG in theory and in fact were 1 374.25 μg/mg and 1 370.17 μg/mg, respectively. The results of structural characterization of the samples revealed the existence of the adsorption of FA on AG which creating a new complex.
