Abstract

We report here a new simple effective spectrophotometric simultaneous determination of Cobalt (II) and Iron (III) with Res-acetophenone guanylhydrazone [RAG]. A standard procedure of the absorption spectra of the reagent and the complex is recommended. The absorbance measurements of Co(II) are carried out at 415 nm [Molar extinction co-efficient is  0.4426 x 10⁴ lit. mole cm^-1] and at 520nm [Molar extinction co-efficient is  0.1230 x 10⁴ lit. mole cm^-1] while of Fe(III) at 415 nm [Molar extinction co-efficient is  0.1223 x 10⁴ lit. mole cm^-1] and at 520nm [Molar extinction co-efficient is  0.2016 x 10⁴ lit. mole cm^-1] at pH 7.6.  The method is applied for the determination of Cobalt and iron in steel alloy and synthetic mixtures.
