Section: claims

1. An apparatus for carrying out a process for purifying Mo-99, the apparatus comprising:a column or vessel containing an adsorbent comprising a zirconium oxide, zirconium hydroxide, zirconium alkoxide, zirconium halide and/or zirconium oxide halide; a source of a solution of a strong base, the source of strong base solution being arranged in fluid communication at an inlet of the column or vessel containing the adsorbent;a column or vessel containing an anion exchange material on which Mo-99 can be quantitatively adsorbed and arranged in downstream fluid communication with the column or vessel containing the adsorbent;a source of a solution of an acid, the source of acid solution being arranged in fluid communication at an inlet of the column or vessel containing the anion exchange material; anda column or vessel containing MnO2 material and arranged in downstream fluid communication with the column or vessel containing the anion exchange material;a source of a solution of sulfuric acid containing thiocyanide ions and a reducing agent, the source of sulfuric acid solution containing thiocyanide ions and a reducing agent being arranged in fluid communication at an inlet of the column or vessel containing the MnO2 material;and a column or vessel containing an ion exchange material comprising iminodiacetate groups and arranged in downstream fluid communication with the column or vessel containing the MnO2 material. 2. An apparatus of claim 1, wherein the adsorbent further comprises a titanium oxide and/or silicon oxide. 3. An apparatus of claim 1, wherein the zirconium compound is present at a concentration of from 5 to 70 mol % of the adsorbent. 4. An apparatus of claim 1, wherein the adsorbent is in the form of pellets.
