Abstract: The equilibrium sorption amounts of the surface active agents onto nylon film and their desorption rates from the nylon which sorbed the solutes into various liquids were measured by using the radioactive sodium hexadecyl sulfate and sodium tetradecyl sulfate tagged with S35. In the sorption isotherms of these detergents, the abrupt increases of the sorption amount were clearly observed near the respective cmc. The desorption rate into pure water rised abruptly at the concentration corresponding to cmc as it was plotted against the equilibrium concentrations of the detergent solution in the sorption test. In 0.1 N sodium chloride solution, the difference of the desorption rates between the both sides of cmc was small and in radioinactive detergent solution there was no appriciable difference. These facts were considered to show the difference of the state of sorption between the both sides of cmc. The formation of a surface micelle was predicted in the concentrations higher than cmc, while the chemical adsorption was assumed below cmc.
