| Outline of Final Research Achievements |
We have succeeded in preparing the PVA-based hollow fiber (HF) type ion exchange membranes (IEMs) whose ionic transport properties of the obtained PVA-based IEMs to evaluate the relationship between the transport properties and the preparation conditions. Ion permeation experiments in Donann dialysis, the value of ion flux (J) and ion permeability (P) showed constant value independent of glutaraldehyde (GA) concentrations. As a result, selectivity coefficient increased as GA concentrations increased. The flux of HF membranes was almost equal to or greater than that of the commercial IEMs, Neosepta AMX and CMX (ASTOM Corp., Japan). The selectivity coefficient of the HF membranes was lower than the commercial IEMs.
