Abstract
Speciation of niobium(V) in solutions containing up to 2.5 mol/l CsOH was s tudied by UV spectroscopy. The mechanism of niobium(V) extraction by toluen e solutions of tetraoctylammonium chloride and sulfate was investigated by the radiotracer method to find out that niobium(V) is completely recovered with tetraoctylammonium chloride and tetraoctylammonium sulfate up to aqueo us CsOH concentrations of 1 and 0.5 mol/l, respectively.
