Ammonia (NH3) that reacts with nitric or sulfuric acid in the air is the major culprit contributing to the formation of fine particulate matter (PM2.5). NH3 volatilization mainly originates from nitrogen fertilizer and livestock manure applied to arable soil. Cation exchange capacity (CEC) of peat m...

암모니아(NH3)는? | 암모니아(NH3)는 대기 중 황산, 질산 등과 반응하여 황산암모늄, 질산암모늄 등과 같은 2차 미세먼지(PM2.5, secondary particulate matter)를 생성하는 주요 미세먼지 원인물질이다(KEI, 2017). PM2. | |
PM2.5는 2.5 μm 이하 크기의 미세먼지의 특징은? | 5는 2.5 μm 이하 크기의 미세먼지로, 10 μm 이하 크기의 미세먼지인 PM10보다 상대 적으로 표면적이 넓어 질산염, 비소, 납, 수은 등과 같은 유해물질이 더 잘 흡착될 수 있다(Kim et al., 2002). PM2. | |
리그닌 등의 물질을 다량 포함하고 있어 알코올이나 알데하이드, 케톤과 같은 음하전 작용기를 가지는 것은? | Sharma and Forster (1993)에 따르면 피트모스는 200 m2g-1 이상의 넓은 표면적과 95%의 높은 공극률을 가진다. 또한 리그닌 등의 물질을 다량 포함하고 있어 알코올이나 알데하이드, 케톤과 같은 음하전 작용기를 가진다. |
