Variables:
Ambient temperature: 283 - 303 K

Method/Apparatus/Procedure:
250 cm3 bottles were filled with distilled and deionized water and sealed. A measured volume of tetrachloroethene was injected into the bottles through each septum using a microliter syringe. Tetrachloroethene was in excess of the anticipated solubility limit. The bottles were shaken for one hour with a wrist-action shaker and allowed to equilibrate for about three weeks. Samples were then injected into a gas chromatograph equipped with a Carbopack column and a FID detector.The GC was response was compared with the calibration plots.
Source and Purity of Materials:
- Probably a commercial reagent at least 99% pure, used as received.
- Distilled deionized.
Estimated Errors:
Ambient temperature: ±0.5 K (compiler).
Mass concentration (m/v) (1): Not specified.
