Method/Apparatus/Procedure:
Water was saturated with tetrachloroethene in a thermostatted round bottomed flask fitted with a stirrer and a mercury seal. The stirring was continued for several days until equilibrium between the two liquids was established. The analysis of the saturated aqueous solution was carried out using a gas chromatograph. The column was filled with Cromosorb W, impregnated with Apiezon I. The helium carrier gas flow rate was 500 cm3/minute.
Source and Purity of Materials:
- Type "pure" (METU 6-00 No. 6590-70), redistilled and checked by GLC.
- Distilled.
Estimated Errors:
Ambient temperature: ±0.2 K.
Mass concentration (m/v) (1): ±1.74%.
