диоксид урана, пероксид химические свойства, назначение, производство
Методы производства
A boiling 10% solution of uranyl nitrate is treated dropwise with 30% H2O2. The resulting amorphous, white precipitate is filtered on the finest filter possible (membrane or Millipore filter) and washed thoroughly with boiling water. The peroxide, a bright sulfur-yellow after filtration, is first dried in the air on a clay plate, then at 100°C to constant weight, and stored in a vacuum over P2O5.Reaction of (NH4)2[UO2(C2O4)2] ? 3 H2O with H2O2 yields crystalline, nonhygroscopic UO4 ? 2 H2O, which is converted to the dihydrate by storing in vacuum over P2O5.
