title: Extractive photometric determination of vanadium(V) as thiocyanato and azido mixed-ligand complexes with N-hydroxy-N-p-chlorophenyl-N'-(2-methyl-4-chlorophenyl) benzamidine hydrochloride.
abstract: Ternary systems involving thiocyanate or azide (X) and N-hydroxy-N-p-chlorophenyl-N'-(2-methyl-4-chlorophenyl)benzamidine hydrochloride (HOAm) are used for the extraction-photometric determination of vanadium(V) as a VOX(2)(OAm)HOAm complex. A strong synergistic effect is observed. Mn(II), Cr(III), Ti(IV), Zr(IV), Mo(VI) and W(VI) do not interfere. The method has been applied to standard steel samples.
