Prediction of seawater solubility of aromatic compounds
The salting-out effect by seawater constituents on the water solubilities of 11 aromatic compounds, anthracene, pyrene, phenanthrene, biphenyl, naphthalene, p-nitrotoluene, p-toluidine, o-nitrophenol, m-nitrophenol, p-nitrophenol and phenol was investigated. A best fit equation for the salting-out parameters, K, and distilled water solubilities, S/sub 0/, at 20/sup 0/C was found to be K = -0.0298 log S/sub 0/ + 0.114. Seawater solubilities, S, predicted for solutions of ionic strength, I, using the equation log S = (0.0298 I + 1)logS/sub 0/ - 0.114 I were in agreement with observed values within 13% and there were no significant differences between values from the Pacific Ocean seawater and those from 35% NaCl solutions. It was concluded that dissolved organic matter in seawater had an insignificant effect for the test chemicals.
