- •
The mechanism of REE ion adsorption by diglycolamic acid ligands was investigated.
- •
Ether oxygen atoms in the ligands played a crucial role in REE ion adsorption.
- •
Amide oxygen atoms in the ligands also participated in REE ion adsorption.
- •
Exchange of the protons in the carboxylic acid group for REE ions also played a role.
- •
Tridentate chelation by the diglycolamic acid ligands conferred high REE selectivity.
