抄録

A polarographic method has been studied as a way to determine 0.05 to 4%Al contained in ferrovanadium, ferrozirconium and ferrotitanium. According to this method, such elements as Fe,Ti,Zr,V are extracted wholly in the form of cupferrate using benzene ether mixture solution. The organic substances in the aqueous layer are decomposed with nitric and perchloric acids. Afterwards, Al is determined by the polarographic method invented by Willard and Dean(6). It is to be noted that, in the case of a sample like B.S.S. No. 61 ferrovanadium, however, we have to eliminate Ni and Cr previously by means of mercury cathode electrolysis, as it contains a big amount of those elements.
