The spectrophotometric determination of vanadium as thiocyanate in acetone-water medium
A method devised for the spectrophotometric determination of vanadium in acetone-water medium is based on the reaction between vanadium (IV) and thiocyanate. Within the concentration limits tested, Beers law is obeyed.
This method is not as sensitive as the peroxide method, but the vanadium(IV)-thiocyanate reaction product shows greater absorbancy than the blue vanadyl ion. In the absence of interfering elements, the method can be used in place of the volumetric procedure for the determination of macro quantities of vanadium.
