摘要
以大孔强碱型离子交换树脂D208对肝素吸附行为为研究对象,对肝素的吸附平衡和吸附动力学进行研究.以Freundlich和Langmuir公式拟合25℃下的吸附等温线,研究结果表明:用Lang muir式拟合比较理想.D208树脂对肝素的离子交换过程为一级反应,交换速率常数为0.383h-1.
Adsorption equilibrium and kinetics of heparin are studied using strong basic anion exchange resin D208. The adsorption equilibrium could be described with both the Freundlich and Langmuir isotherms equation, the results showed that it can be fitted by Langmuir model better than that by Freundlich model.Anion exchange reaction is a first-order reversible reaction, and the rate constant is 0.383 h\+\{-1\}.
