Rapid potentiometric methods for vanadium and for analysis of ferrovanadium and some vanadium steels

Rapid and reliable potentiometric methods are given for determination of vanadium based on titrating unreacted KBr or KI in H₂SO₄ acid medium with Hg(I) or Hg(II), using silver amalgam as the indicator electrode. The methods are successfully applied to the analysis of ferrovanadium, three varieties of vanadium steels and synthetic mixtures of about identical constitution. In all cases the potential breaks were sharp enough for the accurate determination of the end points.
