Abstract: The adsorption of ionic surfactants (cetyltrimethyl-ammonium bromide, sodium dodecylsulf onate, sodium dodecylsulfate) on the solid silver surface is studied in situ by using the liquid quartz crystal microbalance.The adsorption isotherms obtained indicate that they obey different adsorption mechanisms.The adsorption layer of the surfactants on Ag is not firmly fixed and can be physically desorbed.
