Analyses on Hydrophily and Lipophilicity of Dust in Shanghai Different Traffic Concentration Areas
Based on process optimizing, in this article the dust was made a extraction analysis to investigate the ratio of lipophilic substances, which was collected in shanghai different traffic concentration areas. Also, the samples was made a infrared spectroscopy analysis to investigate the organic groups contained. It illustrates that the ratio of lipophilicity in traffic-intensive areas is higher up to 90.1 percent than in living area which is 33.5 percent, those of Shanghai suburb is the littlest, only 12.3 percent. the main functional groups of dust in Shanghai traffic-intensive areas are amino, associating hydroxyl, benzene ring, alkyl and-SH, which is similar to the main component of organic pollutants in motor vehicle exhaust.
