N,O-donor hybrid heterocyclic extractants have great potential for separation of actinides from lanthanides in spent nuclear fuel reprocessing processes. We demonstrate that this type reagents can be used primary concentration contained eudialyte, a promising mineral containing heavy group lanthanides. With respect to lanthanide ions, the efficiency their extraction decreases series L3 >> L1 > L2, and ≈ L2. For extractant L2 based on 2,2′-bipyridine-6,6′-dicarboxylic acid diamide,...
Eudialyte-group minerals are of scientific interest as important concentrators rare elements (mainly Zr and REE) in agpaitic alkaline rocks a potential source REE, Zr, Hf, Nb, Ta for industrial use. Extraction uranium(VI), thorium(IV), zirconium(IV), hafnium(IV), titanium(IV), scandium(III) by binary extractant based on 1,5-bis[2-(hydroxyethoxyphosphoryl)-4-ethylphenoxy]-3-oxapentane methyl trioctylammonium nitrate from eudialyte breakdown solutions is studied. isotherms were obtained...
The paper studies the structure and basic physical chemical properties of titanate dysprosium powders produced by mechanochemical synthesis from low-temperature modification titanium oxide using X-ray diffraction methods (XRD), scanning electron microscopy, Raman spectroscopy (Raman spectra), transmission analyz. Based on XRD it was found that complete conversion initial oxides into amorphous (Dy 2 TiO 5 ) occurs during mechanical treatment mixture for 30–60 min. Microelectron-diffraction...
