Résumé :

Chromatographic behaviour on paper of molybdenum and vanadium when mixed in the same solution has been studied. Very good qualitative separations have been found for both elements. Quantitative control of these separations has been checked by direct titration of the chromatographed spot on the paper. This technique speeds the whole procedure very much without harming in anyway the accuracy of the determinations. © 1953.
