✦ Synopsis

The adsorption of palladium on an unmodified and dimethylglyoxime-modified activated carbon from nitric acid solution was investigated. The adsorption isotherm and the elution behaviour of palladium as well as the ESCA binding energies of Pd 3d and N 1s indicate different bonding states of the metal. The adsorption of palladium from pure nitric acid solution and from model solutions of nuclear wastes is strong and preferential with both adsorbents. However, the capacity and selectivity of the modified activated carbon is significantly higher.
