报道了钪-钙-茜素S（ARS）异多核络合物极谱吸附波的形成及利用它测定钪的最佳实验条件。用此方法测定了矿石中的微量钪，并初步探讨了该极谱波的性质和电极反应机理。在单扫描极谱上用等摩尔连续变化法和单纯形法测得络合物组成的摩尔比为nSe3+:nCa2+:nARS=2:1:2。
The formation of polarographic adsorption wave of scandium-calcium-alizarin S (ARS) heteronuclear complex and the best experimental conditions for the determination of scandium were reported. The trace scandium in ore was determined by this method, and the nature of the polarographic wave and the electrode reaction mechanism were preliminarily discussed. The molar ratio of complex to nSe3 +: nCa2 +: nARS = 2: 1: 2 was determined by single-shift polarography with equimolar continuous change method and simplex method.
