The results indicated that the effect of pH on adsorption of theanine was not obvious within range of 6~11. The adsorption date fit well into the Freundlich and Langmuir isotherm equation within temperature range of 303~323 K and investigative concentration range. The isosteric enthalpy of adsorption, free energy and entropy of adsorption showed that adsorption of theanine was endothermic and spontaneous.

结果表明：在pH6~11时，pH值对717阴离子交换树脂对茶氨酸吸附量影响不大；在温度303～323K和茶氨酸质量浓度范围内，717阴离子交换树脂对茶氨酸吸附行为符合Freundlich和Langmuir吸附等温方程；热力学参数（吸附焓、自由能、吸附熵）表明此吸附过程是吸热和自发的。

The steps of the mold method are as follows: the mold tool stack is closed to form the cavity; the valve is opened to allow resin to enter the cavity; the valve is closed; the resin is allowed to cool; and the mold tool stack is opened to allow removal of the plastic overcap from within the mold tool stack.
