The synthesis and analytical properties of 2-pyrilydeniminobenzohydroxamic acid (2-PIBHA) as well as its reactivity with inorganic ions are described.The reaction between 2-PIBHA and vanadium(V) was studied and two new methods for determination of vanadium(V) are proposed: one in methanol-water medium (40:60percent,V:V) and the other one using an extraction in isoamyl alcohol.Fundamental charasteristics of the first one are λ = 487 nm, ε = 3518 l/mol.cm application range : 3 to 8 ppm of V(V), Sandell sesitivity (1) : 1.4E-2 μg V(V) cm-2 and for the other one : λ = 485 nm, ε = 5080 l/mol*cm application range : 0.6 to 1.6 ppm of V(V) and Sandell sensitivity : 1.=2E2 μg V(V) methods were applied with sucess to the determination of vanadium(V) in steel.
