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. Since 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.en_US
