摘要：
The specific adsorption of sulfate ions on powdered Cr was studied by a radiotracer technique using 35S-labeled sulfuric acid in low concentration (c<10−3 mol dm−3) in the presence of a large excess of perchlorate supporting electrolyte. The pH and concentration dependence were determined. On the basis of a comparison of the results obtained for Cr2O3 and Cr, it can be assumed that, similar to other metals, the overall sorption behavior of Cr is determined by the protective oxide film present on the surface.
