2-Hydroxybenzaldehyde-5-nitro-pyridylhydrazone (2HB-5NPH) was synthesized and its application to the spectrophotometric determination of iron was studied. The reagent reacts with iron in the pH range 6.0-7.5 to form a yellow coIored 1:2 chelate which is very stable in methanol solution. Beer's law is obeyed in the concentration range 0.05��2.0 ${\mu}gmL^{-1}$ iron and separation procedure using a short column filled with Amberlite XAD-7 nonionic chelating resin is proposed for the spectrophotometric determination of traces of iron. The influence of several ions as interference was discussed. The separation of Fe(III) ion from the mix-ture solution were carried out with the buffer solution (pH 5.0) and 0.25M HCl as eluents.
