Abstract
The mechanism of moisture desorption from both stainless steel and ceramic surfaces is studied. A unique experimental setup was designed and utilized to determine desorption under gas flow conditions by monitoring the moisture concentration at the system outlet. A simple analytical technique that was used to analyze the desorption data so acquired, in an effort to normalize the results and thus make them system independent, is presented. Desorption rate constants for stainless steel and ceramic (85% alumina) surfaces are calculated using this model at a constant temperature
