Abstract:

The characteristics of components and ring number distribution of fluorescence aromatic compounds were studied by using gaschromatography and three dimension total scanning fluorescence. The aromatic compounds contain homologous series compounds of naphthalene, phenanthrene and fluorene.The amount of phenanthrene series is larger than that of other compounds. The next is fluorene series compounds, of which the dibenzothiophen, alkyl , and dialkyl dibenzothiophen are 24%～61%. The result of three dimension total scanning fluorescence indicates that the emission spectra of samples from Bransfield Strait, Antarctic are 350～450nm, the ratios of T 4/T 0 are 58%～67%, which attributes to the predominance of more than five ring compounds.
