INFINITE DILUTION ACTIVITY-COEFFICIENTS AND HENRY LAW COEFFICIENTS OF SOME PRIORITY WATER POLLUTANTS DETERMINED BY A RELATIVE GAS-CHROMATOGRAPHIC METHOD

A simple, fast relative measurement method based on gas chromatography developed recently has been used to determine the infinite dilution activity coefficients and Henry's law coefficients in water of some priority pollutants. We show that this simple method can be used to obtain accurate data quite rapidly, which is especially valuable for screening studies. Further, the infinite dilution activity coefficient and Henry's law coefficient data reported here can be useful for directly estimating environmentally important properties such as solubilities in water, multimedia partitioning, and octanol-water partition coefficients.
