| Résumé : | The photometry of vanadium, chromatographed or not, deposited on the paper as the oxinate, is a reproducible process for 3 μg of this element within ±2.76% approximately. The factors influencing the measurement have been studied, especially the aging of the stains and the presence in solution of other elements. The elements wMch are likely of being found along with the chromatographed vanadium from a steel have been investigated in particular. It is not feasible to adapt this determination procedure in this case. © 1955 Springer-Verlag. |
