The dynamic coupled column liquid chromatographic (DCCLC) method for determining the solubility of polycyclic aromatic hydrocarbons (PAH) in water is described. The DCCLC technique is a very rapid, precise, and accurate method for determining the aqueous solubility behavior of sparingly soluble organic compounds. The agreement of PAH aqueous solubilities and calculated solubility parameters, such as ..delta..Hs, with values that have been previously reported in the literature helps to confirm the validity of this approach. In all cases replicate solubility measurements of the generated PAH solutions at constant temperature were better than +- 3 percent and in most cases better than +- 1%. The lack of an appropriate physical parameter for accurately extrapolating PAH solubilities further enhances the utility of DCCLC method.
