| 摘 要： | 从6种碱性离子交换树脂中筛选得到强碱性树脂IRA-400，考察了该树脂在不同pH值、不同葡萄糖浓度下对富马酸和葡萄糖的吸附及富马酸在该树脂上的静态吸附等温线、吸附动力学及动态吸附与洗脱. 结果表明，在高葡萄糖浓度下，树脂IRA-400对富马酸的亲合力均大于对葡萄糖的亲合力；对富马酸的吸附等温线符合Freundlich方程，方程的特征参数n>1，属优惠吸附；不同pH值下的吸附动力学研究表明，液膜扩散是吸附过程的主要控制步骤，符合Boyd液膜扩散模型，液膜扩散速率常数k￠均小于0.15 min-1；动态实验结果表明，采用去离子水和1.0 mol/L NaOH交替洗脱树脂，可实现葡萄糖和富马酸的有效分离.

| Abstract: | The strong basic resin adsorbent IRA-400 was selected from six basic resins to separate fumaric acid from mixed solution of fumaric acid and glucose.Adsorption behavior of IRA-400 was studied by using static and dynamic adsorption methods, including the fumaric acid and glucose adsorption at different pH and glucose concentrations, static equilibrium adsorption, adsorption kinetics, dynamic adsorption and elution.The results showed that IRA-400 had higher affinity for fumaric acid than glucose at higher glu... |
