摘要：

The sorption of fluoranthene on 4 soils and lava was studied without any cosolvent involved. The adsorption equilibrium was found to be established within 1 hour for both soil and lava. Strong linear isotherms were found in all adsorption experiments and the distribution coefficients (K-d) were highly correlated with the organic carbon contents. log K-oc for all four soils was in good agreement with that predicted from the octanol-water partition coefficient (K-ow) and the aqueous solubility (S-w) of fluoranthene. An inverse temperature dependence was observed and the extent of adsorption decreased with the increase of temperature was predictive of Delta H-s(c), which denotes the enthalpic contribution to excess free energy of aqueous solution.
