Radioactive substoichiometric isotope-dilution procedure for the determination of rare earth metals.
A theory is developed which describes the equilibrium conditions when solutions containing trace metals and substoichiometric amounts of EDTA are extracted with thenoyltrifluoroacetone. Experimental evidence is given to support the theory. A method for the determination of microgram quantities of rare earth metal is outlined as an application.
