Lanthanides
The lanthanide ions "stick" to the resin with various strengths based on their ion size. The lanthanum ion, being smallest, binds most tightly to the resin, whereas the largest ion, lutetium, binds the weakest. The lanthanides are then washed out of the ion exchange column with various solutions, emerging one at a time, and so are separated.
