摘要：目的 研究大孔树脂对灰树花子实体多糖酶解液色素的吸附过程和行为.方法 测定S-8树脂对多糖色素的吸附量,绘制吸附动力学和热力学曲线,并对结果进行模拟,确定相应的动力学和热力学模型参数.结果 拟二级动力学方程可更好地描述S-8树脂对色素的吸附过程;热力学结果表明3种双参数模型对色素在S-8大孔树脂上的吸附均有较好的适用性,适用性依次Langmuir＞ Temkin＞ Freundlich;树脂对多糖色素的吸附焓变和吸附熵变均大于零,吸附自由能小于零,平均吸附能小于20 kJ/mol.结论 S-8树脂对色素的吸附过程是自发进行的单分子层物理吸附,在293～ 313 K范围内,升温有利于吸附过程的进行.
AIM To study S-8 macroporous resin＇ s performance in improving adsorption of pigments from enzyme-microwave extract of Grifola frondosa fruiting body. METHODS S-8 macroporous resin＇ s pigments ad- sorption quantities were measured, and the curves of the adsorption thermodynamics and kinetics were simulated and their parameters were calculated. RESULTS The adsorption course can be reasonably demonstrated by the pseudo-second-order kinetics model. The thermodynamic data showed three types of two-parameter models （ Langmuir 〉 Terkin 〉 Freundlich） could describe the thermodynamic behavior of pigments adsorption. The ther- modynamic parameters were found to be AH0 〉 0, AGO 〈0, AS0 〉 0, respectively, with an average energy ad- sorption less than 20 kJ/mol. CONCLUSION The adsorption process of S-8 resin is believed to be spontane- ous and monomolecular physical. Within the range of 293-313 K, an elevated tempeture helps to increase the ad- sorption quantity.
