Quick Summary

Elution is the process of extracting or removing a substance from a solid material using a solvent. In chemistry, this is often seen in chromatography, a technique used to separate components of a mixture.1234

In elution chromatography, a mobile phase (a liquid or gas) carries the sample through a stationary phase. As the mobile phase moves, it carries the dissolved substances, known as the eluate, with it. Different substances will interact with the stationary phase to varying degrees. Those that interact less strongly will move through the system more quickly and emerge first, while those that bind more strongly will be retained longer and emerge later. This process allows for the separation and collection of individual components from a complex mixture.3567

In the second process, elution, a thin layer of ions is introduced at the top of a column already saturated with ions of a second kind; it then is washed down the column with the same kind of ions that saturated the column at the start. In elution, the…

…have been separated using a cation- (positive-ion-) exchange process. The striking similarity between the patterns of behaviour exhibited by the two groups in this process constitutes strong support for the actinoid concept. Nobelium, for example, exists in aqueous solution in the dipositive oxidation state, which might be expected for the…
