초록

Condensation of water can affects the morphology of particulate matter (PM) produced from burning hydrocarbon fuel and thus their refractive index, eventually resulting in changes the light scattering properties of particles. Optical characterization of particulate matter in the air is an essential research to reduce uncertainty in terms of environmental and climate models. However, research results on the effect of hygroscopicity of particulate matter on optical properties are relatively insufficient. Therefore, in this study, optical chracteristics were studied through physical and chemical analysis of Ultra Low Sulfur Diesel (ULSD) particulate matter produced under different relative humidity conditions. Transmission Electron Microscope (TEM) image analysis, Raman spectroscopy analysis and Elemental Carbon(EC)&Organic Carbon(OC) ratio were performed for particulate matter at each relative humidity. As a result, the ULSD particulate matter reacted with water to collapse the agglomerate structure into a compact form, thus predicting an increase in the light scattering effect.
