Several batch adsorption experiments with naphthalene have been carried out. The determined organic carbon-water partition coefficients ranged from 378 to 664. In the course of the adsorption experiments it has been revealed that naphthalene adsorbs to the soil material to a moderate extent, reaching equilibrium state within a period of one day. In contradiction, desorption experiments showed that only 30-50 % of adsorbed naphthalene could be desorbed. The desorption experiments clearly highlighted the strongly dependence of the adsorption rate on the level of the soil contamination: adsorption to soils, contaminated with unleaded gasoline was found to be significantly higher on a soil contaminated with residual hydrocarbons than on a pristine soil. This findings indicate that naphthalene adsorption to residual hydrocarbons was greater than to natural soil organic carbon.
