Abstract
Scandium forms a beta-type complex with p-acetylchlorophosphonazo (CPA pA) in acidic medium, In the presence of cerium, a cocolouration effec t was observed due to the formation of a mixed polynuclei complex [Sc- Ce-(CPApA)(2)], In this paper, the transformation reaction between alp ha-complex of scandium-CPApA and beta-complex was studied kinetically and the mechanism of the formation of the ternary complex was discusse d, Finally, the cocolouration effect of scandium on RE-CPApA system ha s also been discussed.
