1. A method for isolating molybdate from a mixture of fission products comprising:
introducing the mixture of fission products, including a molybdenum compound and a hydroxide source, to a first aqueous solution to produce a fission product aqueous solution;
wherein the hydroxide source reacts with the fission products to produce fission product salts in the fission product aqueous solution;
wherein the hydroxide source reacts with the molybdenum compound to produce a molybdate salt in the fission product aqueous solution;
contacting an organic component comprising a phase transfer agent (PTA) and an organic solvent with the fission product aqueous solution;
wherein the PTA reacts with the molybdate salt to produce a PTA-molybdate complex in the organic component;
isolating the organic component from the fission product aqueous solution; and
eluting the organic component to isolate the molybdate from the PTA-molybdate complex.
