Technetium Reduction

Chemical Formula: Tc, TcO4
Present as: specialty

Technetium is a chemical element with symbol Tc and atomic number 43. It is the lightest element of which all isotopes are radioactive; none are stable. Only one other such element, promethium, is followed (in the periodic table) by elements with stable isotopes. Nearly all technetium is produced synthetically, and only minute amounts are found in the Earth’s crust. Naturally occurring technetium is produced as a by product of the fission of uranium or plutonium in nuclear reactors. The chemical properties of this silvery gray, crystalline transition metal are intermediate between rhenium and manganese.
Many of technetium’s properties were predicted by Dmitri Mendeleev before the element was discovered. Mendeleev noted a gap in his periodic table and gave the undiscovered element the provisional name ekamanganese (Em). In 1937, technetium (specifically the technetium-97 isotope) became the first predominantly artificial element to be produced, hence its name (from the Greek τεχνητός, meaning “artificial”, + -ium).
There are no commercial uses of Tc99 but the meta stable allotrope, TC99m is sometimes used in nuclear medicine.

Pertechnetate, formed in nuclear reactors as a byproduct of the fission of uranium or plutonium has no commercial uses. It can be removed from water using strong base resins with higher amines, notably tributylamine, etc.
