| Abstract: | A simple and sensitive spectrophotometric method has been developed for the determination of zirconium(IV) in aqueous medium. The metal ion forms golden yellow coloured, soluble complex with 2,4-dihydroxy benzaldehyde isonicotinoyl hydrazone (2,4-DHBINH) at pH 1.5 with λmax at 410 nm. Beer's law is obeyed in the range 0.40-4.00 μg ml-1 of Zr(IV). The molar absorptivity and the Sandell's sensitivity of the method are 1.82×104 lit mol-l cm-1 and 0.005 μg cm-2, respectively. The interference of various ions has been studied. The complex has a 1:2 [Zr(IV):2,4-DHBINH] stoichiometry. A method for the determination of zirconium(IV) by first order derivative spectrophotometry has also been proposed. |
