| 摘 要： | 选择NTR7450膜对L-苯丙氨酸和L-天冬氨酸水溶液进行了纳滤分离过程研究,讨论了不同pH下氨基酸的透过特性.在pH=5～8时,NTR7450膜对L-苯丙氨酸和L-天冬氨酸的截留率分别为0和90%.根据实验结果进行了模拟计算.结果表明,通过调节pH值,L-苯丙氨酸和L-天冬氨酸可以被有效地分离.

| Abstract: | The permeation experiments of L-phenylalanine and L-aspartic acid aqueous solution were carried out with NTR7450 membrane. When pH=5~8 the rejections to L-phenylalanine and L-aspartic acid by NTR7450 membrane are about 0 and 90%, respectively. The concentration and separation process of phenylalanine and aspartic acid solution was simulated. The results showed that L-phenylalanine and L-aspartic acid can be separated satisfactorily by adjusting the pH value. |
