Methodology:
Henry's law constants were measured by EPICS and Batch Air Stripping Methods. The Equilibrium Partitioning in the Closed Systems technique compares the GC peak heights upon direct injection of headspace samples. In the Batch Air Stripping Method, equal volume samples were placed in serum bottles and the equilibrated headspaces contained concentrations proportional to original concentrations in the aqueous samples. Full equilibrium was achieved in a few hours.
Sample Information:
- Source and purity not given.
- Distilled.
