Abstract
Perchloric acid is used for oxidation of vanadium and found that perchloric acid quantitatively oxidizes the vanadium. This fact is applied for the quantitative determination of vanadium in steel and established a new analytical method. Since the presence of chromium in this method causes the distubance, it is vaporized as chromic chloride by heating with sodium chloride. A few new facts have been found in connection with this procedure and these are described herein. The procedure in this method can be carried out in 11-18 minutes, its manipulation is simple and the result showed better precision than heretofore known methods.
