Abstract: In this paper, adsorption behavior of proanthocyanidin extracted from grape seed on X-5 macro porous adsorptionresin was studied. In experiment conditions the adsorption equilibrium time was 60min; The results of experiment indicated thatadsorption isotherm was correlated with a Freundlich-type of isotherm equation. The dynamic adsorption capacity measuredfrom breakthrough curve was 164.6mg/g resin, the total transfer mass coefficient 0.018s-1, and the height of mass transfer zone15.9cm.
