A potentiometric study was made of the chelates formed by the uranyl ion with the amino, hydroxy, and mercapto analogs of acetic, propionic, and succinic acids. The order of decreasing stability was aspartic, BETA -alanine, glycine, malic, thiomalic, BETA -hydroxypropionic, glycolic, and thioglycolic acids. The stability of chelates with analogs of acetic, propionic, and succinic acids decreases for any given acid as the donor group changes from NH/sub 2/ to OH to SH. This decrease parallels the order of decreasing basicity in any given series. Considering acids which contain the same donor group (NH/sub 2/, OH, or SH) decreasing stability is observed in the analogs of succinic, propionic, and acetic acids, in that order. (auth)
