Scale-Up Preparation of Uranium Amalgam from Uranyl Ion Using Two-Compartment Electrolyzer

Preparation of U3O8 by Calcination from Ammonium Uranyl Carbonate Using Response Surface Methodology: Process Optimization

The parameters to prepare U3O8 by calcination from ammonium uranyl carbonate were optimized by using response surface methodology. A quadratic equation model for the value of total uranium and U4+ of triuranium octaoxide was built and the effects of main factors and their corresponding relationships were obtained. The statistical analysis of the results indi...

Uranium Ion Yields from Monodisperse Uranium Oxide Particles.

Uranium Removal from Aqueous Solution Using Ion-Exchange Resin DOWEX® 2x8 in the Presence of Sulfate Anions

The current study was attributed to uranium (VI) ions adsorption using a anion exchanger resin, Dowex®2x8, in the presence of sulfate anions. Evaluation of operational parameters including contact time, pH, initial concentration of uranium ions, and presence of various anions (including phosphate, sulfate, chloride, fluoride, and nitrate) in the solution was assessed on sorption performance of ...

effect of two bleaching agent products on mercury and silver ion release from dental amalgam

objective: bleaching of the teeth is considered as a safe, effective, and conservative procedure to treat discolored teeth. the aim of the present study was to compare the amount of mercury and silver released from amalgam after applying two brands of carbamide peroxide 16% bleaching gel. materials and methods: for this experimental study, 384 amalgam tablets were prepared. the samples were kep...
