WebThe extraction study of tetravalent thorium and trivalent rare-earth (Y, La, Eu) ions from acidic nitrate media by B4bL4 in chloroform shows thorium being much more extracted than the rare earths, with selectivity close to 100%. WebApr 11, 2024 · TerraPower Isotopes then processes the Thorium-229 to create Actinium-225, the medical isotope used to develop drugs that can fight cancer. Saved taxpayer dollars and accelerated one of DOE’s highest priority cleanup projects: Isotek reinvested funds it received from TerraPower into the project, helping accelerate the project and begin ...
WebThorium oxide has a melting point of 3300°C, the highest of all oxides. Only a few elements, such as tungsten, and a few compounds, such as tantalum carbide, have higher melting points. Thorium is slowly attacked by water, but does not dissolve readily in most common acids, except hydrochloric. WebDec 25, 2013 · 3.5 Extraction of Thorium by TBP and Third Phase Formation Phenomenon. Pure TBP containing thorium nitrate has a density nearly the same as that of aqueous solutions; therefore the separation of phases is slow when highly concentrated solution is used. Different organic diluents have been used with TBP to increase the …
WebOct 10, 2010 · The maximum extraction of thorium was obtained while 0.001 M hydrochloric acid, 0.001 or 0.01 M thorium and Cyanex272 were used. Under these optimum conditions, the extraction percent and distribution coefficient of thorium were 98.7% and 73.8, respectively. Compared with the hydrochloric aqueous solution, the … WebFeb 18, 2011 · The extraction of thorium was found to decrease with the increase in nitric acid concentration, while the extractions of other elements were increased (except in 0.1 M). Therefore, thorium can only be separated from other studied elements at higher nitric acid concentrations by extracting them in TBP and leaving thorium in the aqueous phase ...
WebSolvent impregnated silica gel material was prepared for thorium recovery from its aqueous nitrate solutions using the neutral phosphine oxide extractant, cyanex-923 in toluene. This was achieved by adsorption of the extractant onto the solid phase in three steps.
