吸附法回收柠檬酸

Recovery of Citric Acid with Adsorption Method

用静态吸附法测定了四种大孔吸附树脂对柠檬酸的最大吸附量，用间歇法测定了不同温度下的吸附等温线，并筛选出一种最适宜的树脂进行了动态测试。用固定床吸附模型模拟了吸附动态过程。计算值与实验值基本符合。

Maximum adsorption quantities of four types of polymeric adsorbents were measured with static adsorption method, the adsorption isotherms under varies temperature had been determined with interrupted method and the most suitable adsorbent was selected for dynamic processes. A fixed-bed adsorption model was proposed to simulate the adsorption dynamic processes. The calculated breakthrough curves were in well agreement with experimental data.
