摘　　要：分别在中空纤维膜和平板膜中考察了 L-赖氨酸超滤动力学 ,结果表明 :中空纤维膜的过滤通量远大于平板膜 ,总过滤时间正相反 ;L-赖氨酸超滤动力学可拟合为浓差极化 -凝胶层模型 。The ultrafiltration kinetics of L-lysine is studied in the hollow-fiber membrane and the plate membrane respectively. As a result, the filtration fluxes of hollow-fiber membrane are far larger than those of plate membrane. Compared with that of the plate membrane, the ultrafiltration kinetics of the hollow-fiber membrane is more in accord with concentration polarization-gel layer model into which the ultrafiltration kinetics of L-lysine is fitted.
