분광분석이란 무엇인가? | 분광분석은 가시광선(Vis)-근적외선(NIR)-단파적외선(SWIR) 파장영역을 기준으로 원소의 종류, 광물의 색 및 결정도 등에 따라 나타나는 반사도 곡선의 형태와 고유의 흡광특성을 파악하는 분석법이다(Shin et al., 2016). | |
산성 광산배수는 무엇을 생성하나? | , 2001). 특히 광산으로부터 흘러나오는 산성 광산배수(Acid Mine Drainage, AMD)는 탄광지역의 하천 수계에 적갈색(reddish brown), 황갈색(yellowish brown) 및 회백색(white)으로 침전물을 생성하며(Kim and Kim, 2002), 각각 적화현상, 황화현상 및 백화현상으로 불린다(Kang et al., 2007; Lim et al. | |
유도결합플라즈마 분석법의 단점은 무엇인가? | 일반적으로 토양 내 유독성 중금속원소의 정량분석을 위해 다양한 분석 방법이 활용되며, 그중 유도결합플라즈마(Inductively coupled plasma, ICP)분석법이 가장 정밀하고 정확한 방법으로 알려져 있다. 그러나, 이 분석법은 전처리 과정이 복잡해 긴 시간이 소요될 뿐만 아니라 그 과정 중 분석물질이 훼손될 수 있으며, 특히 적갈색침전물의 분광학적 특성을 분석함에 있어 분광특성을 보이는 표면과 직접적인 비교분석이 불가능하다는 단점이 있다. 유도결합플라즈마 분석법과는 달리 휴대용PXRF (Portable X-ray Fluorescence)를 활용한 X선형광분석법은 보다 정확한 결과값을 얻을 수는 없으나, 현장에서 빠르게 시료분석이 가능하며 전처리 과정이 없어 분석시간이 짧고, 비파괴 분석이 가능하다(Choi et al. |
