• Abstract The adsorption of barium, mercuric, cupric, aluminum, and thorium ions on the built-up films of stearic acid both transferred from water the surface of water, and converted from barium stearate multilayers, was studied. The adsorbed amount of barium ion increased with increasing pH, but the increase in thickness corresponding to the saturate adsorption for monolayer was constant for all pH. On the contrary, other ions studied showed the specific pH range for the optimum adsorption. A more or less complicated and large structure for these ions was concluded from the special nature of the adsorption hereby exhibited by these ions. Such a complex nature was most pronounced for aluminum and thorium ions.
