Abstract Sodium triphosphate has been used probably for the first time for the ion‐exchange separation of rare earths. A complexing elution on a cation exchanger with sodium triphosphate has given a more satisfactory separation of the light rare earths than the elution of their triphosphato complexes on an anion exchanger with dilute mineral acids. Equilibration studies with Amberlite IRA‐400 resin indicate that the rare earths form anionic complexes with sodium triphosphate over a wide range of p H .
