Аннотация доклада:
This study describes effect of concentrations of two individual extractants such as: Tributylphosphate (TBP), Trioctylmethylammonium nitrate (TOMAN), as well as the composition of isomolar mixtures TOMAN+TBP (1M) on the distribution ratio and seperation factor of rare earth elements. The experiments was carried out at room temperature, from nitrate medium Ln(NO3)3 – (La3+ 1M, Pr3+ 0,5 M và Nd3+ 0,5 M ), NH4NO3 4 M and HNO3 at low concentration 0,01 M, with the volumetric ratio of aqueous/organic phase (O/A) = 1, during contact time and time to separate phase are 15 minutes.
