24-hr integrated measurements of water-soluble organic carbon (WSOC) in PM2.5 were made between May 5 and September 25, 2010, on a six-day interval basis, at the Metropolitan Area Air Pollution Monitoring Supersite. A macro-porous XAD7HP resin was used to separate hydrophilic and hydrophobic WSOC. C...

HULIS가 흥미를 끄는 물질인 이유는? | , 2000). HULIS는 고분자량 화합물의 혼합체이며, 빛을 흡수하고 에어로졸과 안개의 표면장력을 감소 시키는 독특한 성질을 갖고 있기 때문에 흥미를 끄는 물질이다(Kiss et al., 2005; Decesari et al. | |
WSOC 입자의 화학적 특성을 파악하기 위해 이온교환수지법, 고체상 추출기법 및 핵자기공명 분광법을 이용한 기능성 화학적 그룹분리 기법들이 사용되어 온 이유는? | 일반적으로, GC/MS에 의한 개별적인 유기탄소화합물 분석에 의하면 유기탄소 에어로졸의 10~20%만이 구체적인 화합물 형태로 확인이 가능한 것으로 보고되고 있으며, WSOC 화합물이 주로 극성의 산소 함유 유기화합물로 이루어져 있어서 단일성분의 정량화 방법으로는 WSOC 화합물을 확인하는 데 어려움이 존재하였다(Saxena and Hildemann, 1996). 이와 같은 이유 때문에 WSOC 입자의 화학적 특성을 파악하기 위해 이온교환수지법, 고체상 추출기법 및 핵자기공명 분광법을 이용한 기능성 화학적 그룹분리 기법들이 사용되어 왔다(Chang et al. | |
WSOC 입자의 주요 오염원은 무엇인가? | , 1995). WSOC 입자의 주요 오염원은 휘발성 유기화합물의 산화과정을 통하여 생성된 2차 유기 에어로졸(secondary organic aerosol, SOA)로 알려져 있다(Sullivan and Weber, 2006; Bonn and Moortgat, 2003; Odum et al., 1996). |
