The dissolution of tetrachloroethylene (PCE) from the gaseous phase containing PCE to water was studied using an experimental apparatus composed of an aluminium box (25×55×22 cm) covered with a vinyl fluoride film. The dissolution of PCE from the gaseous phase to water was investigated in the state of static sitting. The dissolution rate of PCE from the gaseous phase to water 20 min after the onset of contact was calculated from the data on the relationship between the PCE concentration in water and the contact time. When 0.5, 2.0 and 6.0 ml of the standard PCE gas (80 mg/l) were injected into the equipment, the calculated dissolution rate were 5, 18 and 77 ng/min, respectively. It was shown that the dissolution rate of PCE from the gaseous phase to water was influenced by the PCE concentration in the gaseous phase and by the contact surface area of PCE.
