Sequential Cation-Exchange Separation of Molybdenum-99 and Tellurium-132 from Neutron Irradiated U3O8

Separat1on of Iodine-131 from Neutron Irradiated Tellurium Using Hydrogen Ieroxide

When the former method is employed for production, enriched uranium irradiated for 2-3 weeks in the nuclear reactor is dissoivoc! in nitric acid and the iodine-131 is distilled and collected. '*) But separation of iodine-1 31 from pile irradiated tellurium targets is the most commonly used method of production. The methods <d Reparation varies for different targets. With metal tellurium the tar...

Kinetics study on separation of cadmium from tellurium in acidic solution media using ion-exchange resins.

The feasibility of using ion-exchange resins to separate cadmium from tellurium in acidic solutions of the two metals was investigated. We studied the competitive adsorption of cadmium and tellurium in such resins under varying acid strengths and contact time. We found that low sulfuric acid strength (i.e., 0.5 M) was most effective in removing cadmium from solutions. Different ion-exchange res...

Separation of Uranyl Nitrate Hexahydrate Crystal from Dissolver Solution of Irradiated Fast Neutron Reactor Fuel

A study on separation of 99Mo from neutron-irradiated UO2 by precipitation as ammonium molybdophosphate.

pharmaceuticals has increased so rapidly in the past few yearsl) that the production and the supply of 99Mo are one of the most important missions of an organization for radioisotope production. Molybdenum-99 having enough high specific activity for the medical application can be produced by nuclear fission of 235U. For the separation of 99Mo from fission products have been reported various met...

synthesis of sulfides from alcohols and thiols in solvent-freeconditions and deoxygenation of sulfoxides
