Question

what are the methods employed for separation of Lanthanides

Answer 1

To separate the lanthanides from other elements occurring with them, they are chemically combined with specific substances to form lanthanide compounds with low solubility (oxalates and fluorides, for example). A process known as ion exchange is then used to separate the lanthanides from each other.

Answer 2

The methods employed for the separation of Lanthanides are Ion exchange, valency change.

• Lanthanides are a series of chemical elements.
• The main speciality of lanthanides are they have been widely used as alloys that give strength and hardness to metals.
• These lanthanide series have atomic numbers from 57-71.
• Erbium Er, Cerium Ce are examples of Lanthanide.
• There are many methods to extract lanthanide.
• But nowadays only methods used for the separation of lanthanide is the ion exchange and valency change.
