| Abstract: | In this paper, soluble organics in diesel exhaust particulates were Soxhlet Extracted with methylene chloride and benzene, and the extracts were separated by silica gel column chromatography. The benzene eluates and methylene chloride extracts were analyzed by GC/MS. In comparison with standard mass spectra, a lot of polycyclic aromatic hydrocarbons and aliphatic compounds were identified. |
