By Siegfried Fischer, Jr. INTRODUCTION--LITERATURE ON ELECTROLYTIC VANADIUM. Previous to 1882, very little electrolytic work was done on vanadium, but since then much interest has developed in this field. Electrolytic processes may be divided into (1), those using an aqueous electrolyte, and (2), those using a non-aqueous or fused electrolyte. The electrolytic processes for obtaining metallic vanadium, using either aqueous or fused electrolytes, are very few, and most are of theoretical value only. The literature on the subject is very scant, and much of the data reported lacks accuracy. It is the object of this thesis to determine whether or not it is possible to obtain metallic vanadium from aqueous solutions of its salts. Electrolysis of Vanadium Electrolytes. The literature on electrolytic processes for obtaining metallic vanadium is very scarce, but a considerable amount of work has been done by various scientists on the electrolytic behavior of vanadium compounds. The work is of importance, because in treating an ore or a vanadium product by electrolysis, the vanadium will always be in solution as a compound, which must be decomposed by the electric current. The literature may be conveniently divided into 1. General Literature on Electrolysis of Vanadium. 2. Electrolysis of Aqueous Solutions of Vanadium Salts for obtaining Metallic Vanadium. 1. General Literature. Der Zustand Einiger Ubersaiiren und ihrer Salze (the condition of some super acids and their salts in 3 343675 solution), in the "Zeitschrift fur physikalische Chem.," 43 (1903), 160-178, L. Pissarjewsky studied the conductivity, behavior and composition of the potassium salts of...
