THE ADSORPTION OF SULFUR ON COPPER.
Abstract
A study was made to determine the sites at which sulfur adsorption occurs on copper surfaces. Measurements were made of the relative torques, tau/gamma sub s at the intersection of twin boundaries with surfaces near the three low index orientation, i.e., (100), (110), and (111), over a range of H2S/H2 ratios. H2S concentrations from 3 to 1500 ppm between 830 and 1050C were used. It is concluded that sulfur adsorption occurred perferentially though not exclusively at edge sites near the (100) and (110) surfaces in the H2S range < or = 700 ppm giving rise to negative torques near these orientations. Beyond this H2S range, adsorption occurred at all sites. Near the (111) surface tau/gamma sub s varied little with H2S concentration up to approximately 75 ppm. Above this range, the results indicated that adsorption is occurring on both terrance and edge sites. (Author)
