The study was evaluated and compared to commercial heterogeneous membrane to make cation exchange heterogeneous membrane set up the optimal preparing condition. The research shows that ion exchange resin was added more than 40 wt% to show chemical properties of PVDF higher than commercial heterogeneous membrane. But ion exchange resin was added less than 40 wt% in order to show physical properties of PVDF higher than commercial heterogeneous membrane. According to conditions above, Electrical resistance was measured 1.83 Ω⋅cm-1, water uptake was measured 79%, ion exchange capacity was measured 1.60 meq/g, and burst strength was measured 0.97 MPa. and The TDS remove efficiency was measured by approximately 40%. |
