Impregnating chromium and copper in alumina

The impregnation of spheres of alumina with aqueous solutions of chromium III nitrate and/or copper II nitrate was studied. The solutions were added to the alumina individually, mixed, and sequentially. Chromium III nitrate was strongly adsorbed on the alumina and deposited near the outside of the s...

Summary:The impregnation of spheres of alumina with aqueous solutions of chromium III nitrate and/or copper II nitrate was studied. The solutions were added to the alumina individually, mixed, and sequentially. Chromium III nitrate was strongly adsorbed on the alumina and deposited near the outside of the sphere. Copper II nitrate was less strongly adsorbed and penetrated deeper than the chromium solution. In sequential impregnations, Cr displaced Cu toward the center of the sphere, but Cu moved past Cr initially added to the alumina.
