[1], was used. The general procedure was to add an excess quantity of tetrachloroethene to distilled deionized water, place the sample in a thermostat bath, and mix overnight. A portion of this solution was returned to the stripping vessel. Tetrachloroethene was stripped isothermally from the solution mixture at a known gas flow rate. The Henry's law constant was calculated from the log of the concentration versus time plot. The experimental data values are averages of two or more replicates.", "reference": {"citation": "Mackay, D.; Shiu, W. Y.; Sutherland, R. D. Environ. Sci.
