| Abstract: | A method is proposed for the determination of small amounts of vanadium as found in certain ores, rocks and minerals. After fusion of the sample, the 8-hydroxy-quinoline complex is extracted with chloroform and converted to sodium ortho-vanadate. The absorbancy of this compound is measured at a wavelength of 270 mμ. The present method does not depend on the formation of a colored complex and, hence, is independent of such conditions as time and temperature. |
