Popis: There are at least four major factors which appear to be important in considering adsorption from tbe liquid phase onto solids: (a) the thickness of the adsorbed film, (b) the orientation of the adsorbed molecules, (c) the the liquid components. These factors probably are relevant in the choice of solutes designed to stabilize dispersions. Adsorptton by charcoal from mixtures of benzene with each of the lower aliphatic alcohols is considered in the light of these four factors. Adsorption can be interpreted as being confined to a monolayer, the alcohol molecules being adsorbed with the major axis parallel to the solid surface. The competitive adsorption is affected both by interaction between the liquid components and by strong interaction between the alcohol molecules and oxide complexes on the adsorbing surface. (auth)
