초록

남해연안 갯벌 속에 있는 무기원소들의 정량을 위해 중성자 방사화 분석법과 ICP-AES를 적용하였다. 중성자 방사화 분석법과 ICP=AES에 의하여 얻어진 Al, Ca, Fe, Mg, K, Na의 분석결과들을 상호 비교하였다. 결과적으로 침전물 중의 미량 원소를 분석하는데 ICP-AES보다 중성자 방사화 분석법이 더 우수한 것으로 나타났다. 따라서 중성자 방사화 분석법은 갯벌과 같은 복잡한 모체를 갖는 환결시료들의 분석헤서 중요한 역할을 할 것이다.

Neutron Activation Analysis (NAA) and Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES) have been applied for the determination of inorganic elements in mud flat of south seaside in Korea. The analytical results of Al, Ca, Fe, Mg, K and Na by NAA were compared with those by ICP-AES. The results show that NAA is superior to ICP-AES for the determination of minor elements in sediment. Accordingly, NAA will play an important role in the analysis of environment samples such as mud flat and sediment having complex matrix.
