✦ Synopsis

The adsorption of dimethylglyoxime (DMG) on six commercial activated carbons and on lignite was investigated with the aim to manufacture a modified adsorbent which is capable of separating palladium selectively from metal ion mixtures in nitric acid solutions. The DMG adsorption isotherms and the palladium adsorption behaviour of the modified and unmodified carbonaceous adsorbents indicate strong interaction forces which bring about the adsorption of the reagent. These interactions are probably based on hydrogen bonds.
