ON THE SEPARATION OF VANADIUM, MOLYBDENUM AND ... .
Molybdenum, tangsten, and vanadium are separated by chromatography as peracids, and then detected with tannin solution. Of the seven solvents tested, nbutanolhydrogen peroxidenitric acid mixtures offer the best separations. With the addition of dioxane, the R/sub F/ values of these elements increase, while vanadium and tungsten spots overlap.
