Description

Technical Field

[0001] The utility model relates to the technical field of molybdenum-technetium separation, in particular to a novel molybdenum-technetium chemical separation device. Background Art

[0002] Technetium is a radioactive metallic element, a silvery-white metal, belonging to Group VIIB in the periodic table, and a close-packed hexagonal crystal. Technetium is the first element produced artificially. The main source of technetium is the fission product of uranium in the reactor. It is the lightest chemical element known on earth without a stable isotope. Technetium-99m is the most widely used medical nuclide in clinical diagnosis of nuclear medicine. Molybdenum-technetium chemical separation is generally carried out by solvent extraction, and the solvent extraction method often uses an organic solvent as an extractant.

[0003] During the use of existing molybdenum-technetium chemical separation equipment, organic solvents and molybdenum-technetium are generally placed in an extraction tank for stirring and extraction. However, since molybdenum-technetium is radioactive, it is easy to pollute the external environment when it is dispersed into the air, and it is easy to cause harm when inhaled by the human body. Therefore, we have launched a new type of molybdenum-technetium chemical separation equipment. Utility Model Content
