Method/Apparatus/Procedure:
The apparatus consisted of a stripping vessel similar to that described by Mackay, et al. [1]. The air entered through the top of the vessel and the diffuser was close to the bottom. The solution was added to the stripping vessel and the desired flow rate maintained. Samples of the solution being stripped were taken for analysis. After samples were extracted, they were analyzed by gas chromatograph equipped with a capillary column.
Source and Purity of Materials:
- Source and purity not given.
- pH = 7.6, 370 mg salt/dm3, 60 mg $\ce{CaCO3}$/dm3, 10 mg organic carbon/dm3.
Estimated Errors:
Ambient temperature: ±0.1 K.
Mass concentration (m/v) (1): Not specified.
