  • A simple and rapid technique for radiochemical separation

    A simple and inexpensive method for the separation of medically useful no-carrier-added (nca) iodine radionuclides from bulk amounts of irradiated tellurium dioxide (TeO(2)) target was developed. The beta(-) emitting (131)I radionuclide, produced by the decay of (131)Te through the (nat)Te(n, gamma)(131)Te nuclear reaction, was used for standardization of the radiochemical separation

  • Tellurium Dioxide, Te O 2

    Tellurium dioxide is known in two different crystalline forms. Crystals of the tetragonal system, but almost regular (a:c = 1:1.1076), of density 5.66, are obtainable from the solution in nitric acid, while the molten dioxide when slowly cooled deposits rhombic needles (a:b:c = 0.4566:1:0.4693) of density 5.93 and identical with the rarely occurring mineral tellurite. The formation of

  • How can u separate tellurium dioxide from sulfuric acid

    17/02/2007· Actually, my original problem is separating tellurium dioxide and silicon dioxide. i figured, since both are water insoluble, but TeO2 is soluble in sulfuric acid, and SiO2 isn't, add sulfuric acid to mixture & filter. but then, that leads me to my problem now, that is to separate TeO2 from H2SO4. Or if u know a better way of separating SiO2

  • Separation and purification of 131I from neutron

    29/01/2010· Separation and purification of carrier-free 131 I by the wet-distillation method from thermal neutron irradiated tellurium dioxide targets along with their Al wrappers in 8N H 2 SO 4, HNO 3 and HCl acid solutions containing H 2 O 2 and refluxing for 3 h is investigated. The distilled off 131 I is absorbed in a mixture solution of NaOH + Na 2 S 2 O 3 after passing through 0.5N H 2 SO 4 acid filter.
