Research on the Extraction of 2-Phenylethanol in Fermented Broth by Macroporous Adsorption Resin

Abstract:

In this manuscript,the authors chose HZ816 as research model to study the factors which affect the adsorption and desorption capacity.A series of results were achieved by the single factor experiments: the equilibrium 2-phenylethanol adsorption amount of HZ816 is 151.3 mg/g;the adsorption pH value 5.1;to the adsorption balance time 1.5 h.According to the static balance experiment and isotherm equation,it was found that the behavior of HZ816 obeys to Freundlich equation.Meanwhile,the adsorption of 2-phenylethanol is an exothermic process due to the fact that the 2-phenylethanol adsorption amount of HZ816 decreases with the increasing of temperature.The optimum eluent solvent is absolute ethanol.2-phenylethanol can be desorbed completely by eluent solvent of 3 times bed volume,and the eluting peaks are centralized and no obvious trailing phenomenon was detected.
