  • 2-Hydroxybenzaldehyde-5-Nitro-pyridylhydrazone (2HB-5NPH) was synthesized and its application in the spectrophotometric determination of vanadium ion(IV) was studied in the presence of surfactant. The optimum conditions of pH, solvent effect, concentration of ligand and surfactant were evaluated. The procedure was applied to determination of vanadium (IV) in mixture sample and real sample with satisfactory results (recovery ${\geq}$ 97% ; relative standard deviation ${\leq}$ 3.0% in the concentration range of $0{\sim}1.5{\mu}g/mL$ ; detection limit, $0.02{\mu}g/mL$ in solution).
