液相色谱技术测定葡萄糖果糖在Ca型吸附剂上相平衡常数和总传质系数

Determination of Phase Equilibrium and Lumped Mass Transfer Parameters of Glucose and Fructose on Ca Form Adsorbents by Liquid Chromatographic Technique

考虑轴向扩散的影响,导出液相色谱技术测定吸附相平衡常数和总数传质系数参数估值模型,测定葡萄糖果糖吸附相平衡常数和总传质系数,研究流速、温度对这些参数的影响。获得理论计算与色谱分离实验流出曲线相吻合结果。

Physical and mathematical models used to determine adsorption phase equilibrium and lumped mass transferparameters by liquid chromatographic technique were established, as axial dispersion being taken account. Adsorption phase equilibrium and lumped mass transfer parameters of glucose and fructose on Ca form adsorbents were determined. The effects of velocity and temperature on them were studied. Theoretical elution curves were in good agreement with those from experiments.
