The investigation on the adsorption behaviors of theanine on HD-8 macroporous anion resin were conducted. Effect of PH on adsorption of theanine was not obvious within range of 2~7. The adsorption data fit well into the Freundlich isotherm equation within temperature range of 303~323 K and investigative concentration range. The rate of adsorption was under control by some factors simultaneously such as film diffusion and chemical reaction.
