Abstract: Adsorption process of extracted proanthocyanidins from grape seed into AB-8 macroporous resin was studied.Phase equilibrium equation and adsorption dynamic model for the process were established.Overall mass transfer coefficient,mass transfer zone length and penetration time were calculated at different flow rates and feed concentrations.The results of static adsorption show that the proanthocyanidins adsorption isotherm accords with Langmuir isotherm equation.The dynamic adsorption process of proanthocyanidins to AB-8 macroporous resin is controlled by film diffusion.The calculated penetration time agrees with the experimental results.The theoretical model could be used to supervise adsorption experiment and design.

Key words: macroporous resin, proanthocyanidins, adsorption, theoretical model

摘要: 研究葡萄籽原花青素粗提液在AB-8大孔树脂上的吸附过程,建立了AB-8大孔树脂吸附原花青素的相平衡方程和动态吸附模型,计算了不同流速、不同进料浓度下的总传质系数、传质区长度及穿透时间。实验结果表明,原花青素静态吸附符合Langmuir吸附等温方程式;AB-8树脂对原花青素的动态吸附属于外扩散控制过程;穿透时间计算值与实验值一致。建立的数学模型可用于指导实际生产操作,为吸附柱的设计提供参考。
