초록
방사선 그라프트 중합에 의한 이온교환필터를 이용하여 물에 포함된 미생물의 살균 효과를 연구하였다. 이온교환필터는 부직포 필터에 전자선을 조사한 후, GMA를 그라프트 중합시켰으며, 이 GMA 필터에 이온교환기를 도입시켜 이온교환필터(EtA, DEA, SS)를 도입하였다. 그 결과 이온교환기 밀도는 EtA의 경우 2.38 mol/kg, DEA는 1.79 mol/kg, SS는 0.75 mol/kg으로 나타났다. 이렇게 제작된 필터를 통해 E. coli의 살균력을 측정하였다. SS-diol 필터의 경우 log 4.65로 EtA, DEA에 비해 각각 약 3.00배, 1.10배 높은 제거율이 나타났다. 이는 상수처리 기준 3000 CFU/ml와 비교하여 우수한 결과를 나타냈음을 알 수 있었다.
We studied the pasteurization effect of the microorganism involved in the water, using ion-exchanging filter made of the Radiation Induced Grafted Polymerization. This ion-exchanging filter is made by the graft polymerization of GMA, after irradiation of electron beam to the non-woven filter. Then, we made the ion-exchanging filter (EtA, DEA, SS) applying ion-exchanging base to the GMA filter. As a result, the density of the ion-exchanging base is shown as 2.38 mol/kg in case of EtA, 1.79 mol/kg in case of DEA and 0.75 mol/kg in case of SS. Through this filter made by this method, we measured the pasteurization power of E. coli. We found very high elimination rate such as log 4.65 in case of SS-dial filter, which is higher as 3.00 times in comparison with EtA, and 1.10 times in comparison with DEA. This data show the result is very excellent comparing with 3,000 CFU/ml. of city water treatment basis.
