摘　　要：本文对几种氨基酸稀溶液在其等电点附近,在Na型和H型D61阳离子交换树脂上探讨了它们之间相互作用及有关过程的速率控制步骤(速控步)。结果表明在此类条件下,相互作用包括离子交换作用和离子迁移作用,而其速控步中液膜扩散是主要的。Near the relative isoelectric points, the interactions between the dilute solutions of several amino acids and the Na-D61 or H-D61 cation ion exchange resin were studied. Meanwhile the corresponding determining-rate-steps were examined. According to our results, it follows that both the ion exchange and ionic migration may be involved in such interactions, and the liquid membrane diffusion ought to be most important in the determining-rate-steps.
