Adsorption at the solid/liquid interface plays a decisive role in a wide range of phenomena including the stabilisation of colloidal dispersions, clarification and purification of liquid media (e.g., oil, sugar, liquors, wine), lubrication, and crystal habit modification. Not only the extent of adsorption but the chemical nature and the structure of the adsorbed layer is important. In recent years increasing interest has been attached to the study of molecular structuring phenomena in adsorbed layers. In aqueous media adsorption studies are complicated by the simultaneous influence of elecrical double layer effects, so that, so far, most progress has been made in nonaqueous media. This paper surveys briefly the general problems, and discusses in particular the structuring of n ‐alkanes, n ‐alkanols and n ‐alkanoic acids from the pure liquids and from solution at carbon surfaces. Consideration is given to the possibility that similar phenomena may occur at the aqueous solution/solid interface.
