The optimum conditions for extraction of niobium(V) as a ternary ion-association complex with pyrocatechol and triphenyltetrazolium chloride(TTC) have been determined. The investigation of the composition has shown that the ratio Nb:proocatechol:TTC is 1:2:1 Kex, KD and β have been determined radiometrically, using the chemical model. The influence of foreign ions on the extraction of the ion-association complex has been studied. A method for artifical mixture and steel containing niobium has been used.
