Method/Apparatus/Procedure:
The saturation vessel is drawn in the original paper. (2) was saturated with (10 via the vapor phase: a few drops of a tight-fitting flask filled with water. Complete saturation was reached by shaking overnight in an upright position. Samples were taken from the aqueous solution with a microsyringe through the septum and injected into the gas chromatograph equipped with a flame ionization detector. The gas chromatographic conditions are described in the paper.
Source and Purity of Materials:
- Fluka purum.
- Tap-water was refluxed for eight hours in the presence of $\ce{KMnO4}$ and $\ce{KOH}$ and distilled. The whole process was repeated once more.
Estimated Errors:
Mass concentration (m/v) (1): error given above (90% probability interval)
Components:
- Hexane, $\ce{ C6H14 }$; [110-54-3] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
