On The Validity Of The Codistillation Model For The Evaporation Of Pesticides And Other Solutes From Water Solution

Evidence is presented that disagrees with the concept that the rapid evaporative loss of some low-vapor-pressure compounds from water is due to codistillation. The observation that under certain conditions the solute evaporates while the water vapor condenses demonstrates the absence of mechanistic coupling between water and solute transport. These findings suggest that predictions of the solute evaporative loss in terms of water loss would give uncertain results.
