Abstract: Adsorption equilibrium and kinetics for Puerarin are studied for macropore resin AB-8 used as an adsorbent. The equlibrium temperature could be described with both of the Frundich and Langmuir isotherms equations. The adsorption kinetics curves were simulated and served as base reference for resin adsorption. These equations could be used as the reference and  basis of the study on resin adsorption. The breakthrough curves were determined and simulated by a linear equation. The results are important to the study of a dsorption and the performance of adsorbent.
