A modified gas saturation method was used to determine the solid vapor pressure of perfluorooctanoic acid (PFOA) at ambient temperatures. Measurements were made over the temperature range from (25 to 45)degrees C. Pressures ranged from (5.2 to 40.7) Pa. The enthalpy of sublimation was calculated as 88.9 kJ.mol(-1).
