abstract: On a effectué une étude spectrophotométrique dans l'ultra-violet, des complexes formés par l'acide anthranildiacétique (ANDA) avec le scandium(III), l'yttrium(III) et le lanthane(III) qui a permis de doser ces éléments. On a établi que ces complexes possèdent la composition Me-ANDA = 1:1 et on a calculé leurs constantes d'instabilité apparente : K = 1,5 . 10(-6) pour le complexe Se-ANDA, K = 3,4 . 10(-6) pour Y-ANDA et K = 2,9 . 10(-6) pour La-ANDA. A spectrophotometric study of the complexes formed between anthranil-N,N-diacetic acid, ANDA, and scandium, yttrium and lanthanum, has led to the development of methods for the determination of these elements. The instability constants for the complexes, in which the Me: AND A ratio is 1:1, were found to be 1.5 x 10(-6), 3.4 x 10(-6) and 2.9 x 10(-6) for Sc-ANDA, Y-ANDA and La-ANDA respectively.
