摘要： 报道了锆-钙-茜素S异多核络合物的形成及该异多核络合物极谱吸附波测定锆的最佳实验条件.用此法测定了矿石样品中的微量锆,并探讨了该极谱波的性质的电极反应机理.在单扫描示波极谱上用单纯形法和斜率比法测得该体系异多核络合物的组成比为:nZr(Ⅳ):nCa2+:nARS=1:1:4用分光光度法测定亦得到相同的结论.

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
