A photoacoustic method to quantitatively measure the adsorption of CH3OH on gas-solid interface is presented. The adsorption of CH3OH 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.
