A solvent-extraction spectrophotometric technique is proposed as a new method for determination of trace quantities of vanadium. Sodium salt of 2-mercapto-pyridine-N-oxide (thione) forms a complex with vanadium instantaneously. The purple 1:2 complex

A sensitive kinetic method for determination of vanadium is reported at pH 2 and 25 °C. The catalytic effect of vanadium on the oxidation of indigo carmine by bromate goes through an induction period and then decreases in absorbance at 612 nm, which
