POLAROGRAPHIC CHARACTERISTICS OF NIOBIUM IN PHOSPHORIC ACID SOLUTIONS (in Russian)

OSTI ID:4280794
A polarographic study of phosphoric acid--niobium solutions was carried out. It was found that niobium gives a well developed wave in concentrated phosphoric acid (1.75). The limiting current value has a linear re1ationship to the niobium concentnation in solutions from 0.5 to 50 mM/l. Niobium solutions in phosphoric acid are stable, and the reproducibility of polarograms is good. The half-wave potential increases from 0.6004 to 0.680 v (S.C.E.) with the increase of the niobium concentration (from 0.5 to 50 mM/l). The reduction of Nb(V) in a phosphoric acid solution is irreversible. (auth)
