Uranyl Acetate Adsorption

SERS data gave evidence for U02 ON A-(2-mercaptopropionyl)glycine-modified silver colloid. IR data have been reported for uranyl acetate and oxalate in KBr matrices.U02 species are adsorbed on to colloidal silver and Ag20 surfaces. The VsU02 mode shifts to lower wavenumber on adsorption. 

Ishlmorl and Okuno have Investigated a number of cation exchange systems other than those already noted. Some of their results, D versus sodium sulfate, sodium acetate, and oxalic. acid concentration, are Illustrated In figure 76. The adsorption of uranium by Dowex-50 from solutions of hydroxylamlne was found to be pH dependent. As the pH of the solution was Increased, a sharp decrease In D was observed between pH 5 and 6. Uranyl Ion was not adsorbed by Dowex-50 resin from carbonate solution.
