Author(s): G. Sumathi and T. Sreenivasulu Reddy
Abstract: Determination of zirconium(IV) by direct spectrophotometry and simultaneous determination of zirconium(IV) gives a yellow colour with 2-hydroxy naphthaldehyde-p-hydroxybenzoic hydrozone with 1:1 metal-reagent stoichiometry at pH 1. The complex shows an absorption maximum at 415 nm with molar absorptivity and the molar absorptivity and the Sandell’s sensitivity of the method are 0.986±0.002×104 l mol-1cm-1 and 0.0092 µg/cm2 respectively. Beer’s law is obeyed in the range 0.456-4.56 µg/ml at pH 1.0. Zirconium(IV) and titanium(IV) have been determined simultaneously by measuring the absorbance of the solution mixture at 415 and 405 nm respectively. The method has been applied for the simultaneous determination of zirconium(IV) and titanium(IV) in steel samples.
