Abstract (EN): The behaviour of two crystal faces of gold with extreme surface energies (111) and (210) in aqueous solutions of sulphamic acid was studied. The results indicate the influence of crystallographic orientation (c.o.) in the adsorption of sulphamic acid. The degree of adsorption is intermediate between perchlorate and sulphate, and is reflected on the oxidation process of gold single crystal faces. The results are interpreted in terms of the distortion of the trigonal structure of the anion. © 1989.
