Solubility measurements of naphthalene in seawater of different salinities have been determined by the Generator Column Method in the 276.6 K to 316.8 K temperature range. The Gibbs free energy, enthalpy, and entropy of solution were evaluated at 298 K by means of the Clarke and Glew equation. The temperature dependence of the Setschenow parameters for naphthalene in seawater has been studied and compared with the values calculated using current models for the salting-out of nonpolar molecules. The Surface Tension Approach gives the best correlation with experimental values. Keywords: Setschenow parameters, solubility of naphthalene in seawater.
