Question

Describe the method at isolation of lanthanide ions from mixtures by valence change method and ion exchange chromatography

Answer 1

A process known as ion exchange is then used to separate the lanthanides from each other. In this process, a solution of the lanthanides in ionic, soluble form is passed down a long column containing a resin. The lanthanide ions "stick" to the resin with various strengths based on their ion size.
