A technique is developed for measuring the thermal desorption of one or more gases using the time-of-flight mass spectrometer. With this method the adsorbed population, gas–solid bond energy, and preexponential kinetic factor can be determined for each adsorbed gas. The thermal desorption of nitric oxide from plutonium dioxide was measured over the temperature range 100°–900°C and typical spectra are presented. The activation energy of desorption was found to be 19.4 kcal/mole. The probable mechanism for adsorption is also discussed.
