| Abstract: | Scandium forms a β-type complex with p-acetylchlorophosphonazo(CPApA)in acidic medium.In the presence of cerium,a cocolouration effect was observed due to the formation of a mixed polynuclei complexSc-Ce-(CPApA)2].In this paper,the transformation reaction between α-complex of scandium-CPApAand β-complex was studied kinetically and the mechanism of the formation of the ternary complex was discussed.Finally,the cocolouration effect of scandium on RE-CPApAsystem has also been discussed. |
