ABSTRACT:
A cylinder containing a vacuum lid opening at one end and a tee connector is used as a containment vessel to measure the rate of volatilization of dissolved volatiles from solids. One end of the tee is connected to a vacuum pump and the other end is attached to a vacuum pressure gauge. A thermal sensor is located at the bottom end of the cylinder for monitoring the temperature of the solid material. In operation, a sample of contaminated solid is placed in the cylinder, the vacuum pump is activated and the vacuum pressure and solid temperature are monitored over a period of time. The mass transport coefficient for volatilization of dissolved gases from contaminated solids can be determined from Henry's law and a mass transport equation.
