Abstract
The complexation of uranyl ion (UO 2 2+) and pervanadylion (VO 2 +) with glycine has been investigated by spectrophotometric measurements in aqueous solution at 1 M ionic strength (NaClO 4). The stability constants of the complexes formed and their stoichiometries are given and interpreted. The logarithms of the cumulative stability constant β xyz of the complex: [(H) x(oxometal) y(glycine) z], are, respectively, log β 011 = 9.43 and log β 012 = 17.55 for U(VI) and log β 011 = 11.55 and log β 012 = 19.71 for V(V). The infrared spectra of uranyl and pervanadyl complexes of glycine have been studied in aqueous solution in the 1800-1700 and 1550-900 cm −1 regions. The sectra suggest the coordination of oxometal complexes is by the amino and the car☐ylate groups of glycine.
