Abstract: The formation of zirconium-calcium-alizarin red Smix-polynuclear complex hasbeen investigated.The optimum conditions of the determination of Zr(Ⅳ) by use of the polarographic adsorptive wave of the mix-polynuclear complex have been reported.It can beused for the determination of trace Zr(Ⅳ) in mineral sample.Furthermore, its polarographicbehaviour and the electrode reaction mechanism have been studied.The molar ratio of eachcomponent in the complex has been estimated as nzr(Ⅳ): nca2+: nARs=1: 1: 4

Key words: Zirconium, Calcium, Alizarin red S, Mix-polynuclear complex, Polarographic adsorptive wave
