Variables:
Ambient temperature: 283 - 303 K
Prepared by:
Method/Apparatus/Procedure:
250 cm3 bottles were filled with distilled, deionized water and sealed. Measured volumes of 1,1,1-trichloroethane were injected into the bottles through each bottle septum using a microliter syringe. The solute was in excess of the anticipated solubility limit. The bottles were shaken for 1 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 Carbo-pack column and a FID detector.The GC responses were compared with calibration plots to establish concentrations.
Source and Purity of Materials:
- Probably a commercial reagent at least 99% pure. Used without further purification.
- Distilled and deionized.
Estimated Errors:
Ambient temperature: ±0.5 K (compiler).
Mass concentration (m/v) (1): Not specified.
