A STUDY OF SOLVENT EXTRACTION OF NIOBIUM FROM NITRIC ACID SOLUTION V. AN EFFECT OF SOME METALS ON EXTRACTION OF NIOBIUM WITH TBP

    Graphical Abstract
    • Abstract
  • The paper deals with a behaviour of extraction of niobium with TBP in thepresence of molybdenum and zirconium, uranium, or praseodynium in the aqueousphase. The dependence of extraction of nionium with TBP on the concentrations ofzirconium in 1～8 mol/l HNO_3 is described. The results show: 1. In the concentrations of 1×10~(-3) mol/l
