dc.description.abstract액체섬광계수기(LSC)를 이용한 극미량의 14C-NDMA의 측정과 이를 이용해 활성탄 흡착 처리 가능성을 알아보았다. 14C- NDMA를 측정하기 위한 시료와 섬광용액은 10:10의 혼합비율로 10분의 측정 시간으로 99.9%의 상관성과 재현성을 보이며 1 ng/L까지의 측정이 가능하였으며, S-A(Sigma-Aldrich co.)와 Dj(Daejung co.)의 분말활성탄을 이용하여 흡착 처리한 결과, 50~10,000 mg/L의 분말활성탄을 주입하여 90% 이상의 흡착처리가 가능함을 보였다. 또한 S-A가 Dj보다 흡착능이 약 2배 높게 나타났지만, NDMA의 흡착력이 다른 아민 계열의 물질보다 현저하게 낮아 요구되는 분말활성탄의 농도가 높게 요구되었다.-
dc.description.abstractSince the difficulty of analysis at low concentration and the uncertainty of the removal mechanism for Nitrosodimethylamine (NDMA) have been reported, this study has detected extremely low concentration 14C-NDMA using the LSC(Liquid Scintillation Counter) and tested NDMA removal by Powdered Activated Carbon(PAC). The results showed the highest correlation over 99% when samples were measured with the mixture ratio of sample to scintillation liquid of 10:10 and at the detection time of 10 min. For 14C-NDMA removal by the PACs(S-A(Sigma-Aldrich co.) and Dj(Daejung co.)) raging from 50∼10,000 mg/L, 14C-NDMA was removed over 90% by adsorption treatment. In addition, S-A showed twice greater adsorption capacity than that of Dj. However, the required PAC amount for 14C-NDMA removal was higher than that of other amine compounds.-
