Water solubilities of solid solution forms of phenanthrene and anthracene in water between 283 K and 308 K were measured by the shake flask method. The present experimental results showed that solid composition affected the water solubility of the solid solution as follows: The saturation concentration of a solute decreased with an increase in the amount of the other in the solid phase. In particular, this solubility decrement was remarkable within a low concentration range of anthracene in the solid solution. Within the same range, furthermore, the temperature dependence of the anthracene water solubility increased while that of phenathrene decreased. Finally, we tried to calculate the solubility behavior, based on the fugacity ratio between the liquid and solid phases and an activity coefficient model.
