열유도 상분리법에 의한 고밀도 폴리에틸렌 중공사막의 제조(IV) - 금속이온 흡착 한외 여과막 - = High Density Polyethylene Hollow Fiber Membrane via Thermally Induced Phase Separation(IV) -Metal Ion Adsorbent Ultrafiltration Membrane-

다국어 초록 (Multilingual Abstract)

Hollow fiber membrane, containing amidoxime group has been prepared via AN grafting on to the plasma treated high density polyethylene(HDPE) membrane for ultrafiltration(UF), followed by amidoximation of the nitrile group of the grafted chain. It was found that cupric ion in the aqueous phase, is efficiently exhausted by the amidoximed membrane in water purification. This means that the modified UF hollow fiber membrane is very useful not only for the removal of microorganisms but also for the removal of the various metal ions from the aqueous phase. The effect of % graft on the water permeability of the membrane and the exhaustion of the metal ion dissolved in water under relatively low operating pressure of the water purification process was also discussed in relation to the morphological change of the membrane in various treatments.
