摘要/Abstract

摘要：

以NKA-9 型树脂对光皮木瓜多酚的吸附行为为研究对象，对多酚的吸附平衡进行研究，在温度298～308K和浓度20～40mg/mL 的范围内，NKA-9型树脂对光皮木瓜多酚吸附的平衡数据符合Langmuir 和Freundlich 等温吸附方程，且为优惠吸附。对光皮木瓜多酚在NKA-9 型树脂上的吸附焓、吉布斯自由能和吸附熵进行计算表明，该吸附过程是一个吸热过程。

关键词: 木瓜多酚, NKA-9型树脂, 吸附平衡, 吸附热力学

Abstract:

Thermodynamic adsorption characteristics of Chaenomeles sinensis polyphenols onto NKA-9 resin were studied. Results showed that adsorption equilibrium data obtained within the temperature range of 298－308 K and concentration range of 20－40 mg/mL could be well fitted by the Langmuir-type and Freundlich-type isotherm equations and the adsorption was favorable type. Meanwhile, the changes of enthalpy, free energy and entropy were measured. It was indicated that the adsorption was an endothermic process.

Key words: Chaenomeles sinensis polyphenols, NKA-9 resin, adsorption equilibrium, adsorption thermodynamics
