| Abstract: | The specimen are dissolced in orthophoric acid. Then excessivehydrogen nitrate is added into the solution to break down the carbide,theelement,vanadium,is oxidized quantitively unedr high temperature and deacidized with ferrousammonium sulfate. so,the content of vanadium can be calculated according to the amount offerrous ammonium sulfate consumed. |
