Method/Apparatus/Procedure:

An aqueous solution with an excess amount of trichloromethane was stirred for one day before being introduced into a 1 L glass vessel. Nitrogen entered at the bottom of the vessel through a sintered glass disk. The exit gas flow rate was measured by a soap bubble flow meter. The concentration of trichloromethane in water was determined using gas chromatography. The GC was equipped with both dual flame ionization detector and an electron capture detector.
