摘要
本文建立了测量芳香氨基酸在吸附树脂上传质速度的方法。引用Boyd方程模型测定了苯丙氨酸和酪氨酸的有效内扩散系数;研究了树脂结构与芳香氨基酸扩散速度之间的关系;同时考察了温度、pH值诸因素对扩散速度的影响。
A new method was established to detect the mass transfer rate of aromatic amino acids (Phe and Tyr) on the porous adsorbent. According to Boyd' s equation model, the effective interdiffusion coefficients of amino acids were determinated. The relationship between the adsorbent structure and the rates of diffusion of aromatic amino acids was studied. The effects of temperature and pH on the diffusion rate were also investigated.
