Abstract
Methods for purifying the molybdenum-99 isotope are disclosed. Molybdenum-99 is loaded onto an anion exchange column and extracted. In some embodiments, the extraction solution may include nitric acid and nitrate salts. In other embodiments, a two stage elution is performed in which a nitric acid containing eluent and a hydroxide containing eluent are used in succession to extract molybdenum-99.
Claims18
A method for purifying a molybdenum-99 feed stream comprising molybdenum-99, the method comprising:
- contacting the molybdenum-99 feed stream with anion exchange media to adsorb molybdenum-99 onto the media;
- and
- contacting the molybdenum-99 adsorbed media with an eluent solution comprising nitric acid and a nitrate salt.
A method for purifying a molybdenum-99 feed stream comprising molybdenum-99, the method comprising:
- contacting the molybdenum-99 feed stream with anion exchange media to adsorb molybdenum-99 onto the media;
- contacting the molybdenum-99 adsorbed media with a nitric acid-containing eluent solution;
- and
- contacting the molybdenum-99 adsorbed media with a hydroxide-containing eluent solution containing hydroxide at a concentration of at least 0.1 M.
