Abstract:

 A photoacoustic method to quantitatively measure the adsorption of CH_3OH on gas-solid interface is presented. The adsorption of CH_3OH on such commonly used materials as quartz, pyrex, polytetrafluoroethylene teflon, petheoroalcoxy teflon and polished stainless steel SS316 is measured. Kinetic simulation can explain the experimental results, thus providing a basis for the generalization of the experimental results. The adsorption property of the materials at reduced temperature is also studied.
