Method/Apparatus/Procedure:
The isotope dilution technique was used. It involved the mixing of about 100 mL tetrachloromethane with 1 mL heavy water in a volumetric flask which was then inserted into a constant temperature bath. The mixture was agitated for 15 minutes to ensure the equilibrium between the two phases. The radioactivity of the samples were determined by a liquid scintillation counting procedure.
Source and Purity of Materials:
- Received from pile EL 3 of Saclay, contained traces of tritium.
- Source not given, commercial grade.
Estimated Errors:
Ambient temperature: ±1 K (compiler).
Mass concentration (m/v) (1): ±0.4 × 10-5 g.
Components:
- Water-d2, $\ce{ D2O }$; [7789-20-0] NIST WebBook
- Tetrachloromethane, $\ce{ CCl4 }$; [56-23-5] NIST WebBook
