METHOD FOR SEPARATION OF ADJACENT LANTHANIDE ELEMENTS
Lanthanide complexing molecules having the following structure:
##STR00001## wherein: R.sup.1, R.sup.2, R.sup.4, and R.sup.5 are independently selected from hydrogen atom, alkyl groups containing 1-3 carbon atoms, and hydrophilic groups containing at least one oxygen atom; R.sup.3 and R.sup.6 are independently selected from hydrogen atom, alkyl groups containing 1-3 carbon atoms, and hydrophilic groups containing at least one oxygen atom; and R.sup.a and R.sup.b are independently selected from hydrogen atom, methyl group, halogen atoms, and hydrophilic groups containing at least one oxygen atom; wherein at least two of R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6, R.sup.a, and R.sup.b are said hydrophilic groups. Also described is a method of separating adjacent lanthanides by use of a two-phase extractant system that includes (i) an acidic aqueous solution containing the lanthanide complexing molecule (1) along with a mixture of at least two lanthanides, and (ii) an aqueous-insoluble hydrophobic solution containing a lipophilic lanthanide extractant compound.
