摘　　要：本文研究了Sc,Ca,ARS体系共显色效应。通过实验表明,此共显色效应是由于形成聚合型异多核配合物所致,并且对一定范围钪量成线性关系。用此法可进行微量钪的测定。最后还探讨了该聚合型异多核配合物形成的机理。The cocolouration effect of Sc-Ca-alizarin red has been investigated. The essence of the cocolouration effect is due to formation of polymoric mixed polynuclear complexes. And there is a good linear relationship between the concentration of trace scandium and the absorbance. This method was used to determine microamount of Sc. The possible mechanism of formation for the polymeric-mixed-poly-nuclear complexes has been discussed.
