Method/Apparatus/Procedure:
The method involved repeated equilibrations of nitrogen with seawater sample containing trichloromethane. The sample was shaken vigorously at the required temperatures in a constant temperature bath for 30 minutes. The equilibrated gas phase was then injected into a gas chromatograph. The experiments were performed at least three times at 10, 15, 20, and 25 °C, each experiment involving about six equilibrations.
Source and Purity of Materials:
- Source and purity not given.
- Salinity = 20%.
Estimated Errors:
Ambient temperature: ±0.5 K (compiler).
Mass concentration (m/v) (1): See above.
Components:
- Trichloromethane, $\ce{ CHCl3 }$; [67-66-3] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
