Abstract
Provided are methods to separate an isotope from a first solution including uranium. The methods may include (a) cleaning the first solution to form a second solution including the uranium and a third solution including the isotope; (b) oxidizing the third solution to form an oxidized isotope; and (c) separating the oxidized isotope.
Claims17
A method of separating a desired isotope from a first solution comprising uranium, the method comprising:
- a) cleaning the first solution to form a second solution comprising uranium and a third solution comprising the desired isotope;
- then
- b) oxidizing the desired isotope;
- and then
- c) applying the third solution to a medium to separate the desired isotope from the third solution, wherein the medium does not include a solvent extraction process, and wherein the desired isotope is selected from the group consisting of Mo-99, I-131, I-125, In-111, Xe-133, Y-90, Pd-103, Ru-106, and Cs-137.

A method of producing desired isotopes, the method comprising:
- a) irradiating a uranium solution to form a first solution comprising uranium and a daughter isotope;
- then
- b) contacting the first solution with a chemical separation medium to form a second solution comprising the uranium and a third solution comprising the daughter isotope;
- and then
- c) oxidizing the third solution and then applying the third solution to a medium to separate the daughter isotope from the third solution, wherein the medium does not include a solvent extraction process, and wherein the daughter isotope comprises a desired isotope selected from the group consisting of Mo-99, I-131, I-125, In-111, Xe-133, Y-90, Pd-103, Ru-106, and Cs-137.

A method of producing isotopes, comprising:
- a) irradiating a uranium solution to yield a daughter isotope;
- then
- b) separating the remaining uranium from the solution;
- then
- c) oxidizing the daughter isotope;
- then
- d) applying the solution to a medium to separate the daughter isotope from the solution, wherein the medium does not include a solvent extraction process;
- and then
- e) extracting the daughter isotope, wherein the daughter isotope comprises a desired isotope selected from the group consisting of Mo-99, I-131, I-125, In-111, Xe-133, Y-90, Pd-103, Ru-106, and Cs-137.
