Abstract

Henry's Law constants were measured for 45 chemicals spanning a wide range of chemical structures and volatilities. A static headspace method, Equilibrium Partitioning in Closed Systems (EPICS), was used to measure Henry's Law constant, and the batch air stripping method was used as a check. Measurements were conducted over a temperature range of 10–30°C, and the data were correlated with a temperature regression equation. An average precision of 10% was obtained for the EPICS runs, and the Henry's constants agreed well with the batch air stripping results and other reported values.
