  • The development of an extraction strategy based on EHEHP-type . . .
    Therefore, HREEs are more important than LREEs since the supply risk and importance to clean energy 2-ethyl (hexyl) phosphonic acid mono-2-ethylhexyl ester (HEH [EHP], P507) is the most widely used extractant for individual REE separation in Chinese rare earth industry Because of the well performance, HEH [EHP] has been applied for decades
  • Multiplicity of Th (IV) and U (VI) HEH [EHP] Chelates at Low . . .
    A better understanding of the variability of HEH [EHP]–actinide complexes and the speciation of chelates for tetra- and hexavalent actinides can improve the predictability of actinide phase transfer in such biphasic systems In this study, the extraction of Th (IV) and U (VI) from nitric acid media using HEH [EHP] in heptane is examined

  • Investigation of the hydrolytic and radiolytic degradation of HEH[EHP]
    Introduction The extractant 2-ethylhexylphosphonic acid mono-2-ethylhexyl ester (HEH[EHP]) is a component used in both the Advanced TALSPEAK and ALSEP solvent extraction processes The most likely compound formed via hydrolytic or radiolytic degradation of HEH[EHP] would be the phosphonic acid 2-ethylhexylphosphonic acid (H2EHP) that is formed by cleavage of the P-O-R bond Thus far, attempts
  • Selective recovery of rare earth elements from ion-adsorption rare . . .
    Based on their different extraction abilities and a cation-exchange mechanism, two acidic phosphorus extractants (HEH (EHP) and HDEHP) were selected to sequentially separate and enrich REEs Using this novel technique, ammonia nitrogen emissions were completely avoided and the recovery efficiency of REEs was significantly improved
