THE SOLUBILITY OF CARBON-TETRACHLORIDE IN WATER AND SEAWATER

High precision measurements of the solubility of carbon tetrachloride (CCl4) in pure water and seawater were made over the temperature range of similar to 0-40 degrees C, For comparison with previously reported results, the solubilities of CFC-11 and CFC-12 were also measured dur ing these experiments. The experimental data were fit by equations in temperature and salinity, in the form used in previous gas solubility studies, The CFC-11 and CFC-12 results were generally in good agreemen t with earlier work, although some differences were noted, For CCl4, t he standard error of the measurements from the fitted curves was +/- 2 .5%. The concentrations of dissolved CCl4 measured in near-surface wat ers on a recent long meridional section in the South Pacific Ocean (wh ere the temperature ranged from -1 to 29 degrees C) ale compared to ca lculated saturation levels based on these solubility data and atmosphe ric levels of CCl4 measured along the section.
