Methodology:
The multiple equilibration technique with direct aqueous injection into a gas chromatograph was used to determine the dimensionless Henry's law constant. A known volume of liquid and gas was introduced into a syringe and allowed to equilibrate. The ratio of gas to liquid volume was maintained constant. While vapor samples were injected directly into a gas chromatograph, the liquid samples were preconcentrated by liquid-liquid extraction before analysis. The experiments were carriedout in duplicates.
