Description
The stability constants of the complexes of uranyl and neodymium ions with glutanic acid are determined pH-metrically in 0.1 M NaClO4 solution at 250C. In both cases protonated complexes are formed in significant concentrations. A new MA complex is found in the uranyl glutamic acid system. In accordance with this investigation a graphical treatment of the visible spectral data gives the molar absorption coefficients of both MA and MHA species. (orig.)
Abstract (German)
Die Stabilitaetskonstanten der Uranyl- und Neodymkomplexe von Glutaminsaeure wurden pH-metrisch in 0,1 M NaClO4-Loesung bei 250C bestimmt. In beiden Faellen werden in betraechtlichen Konzentrationen protonierte Komplexe gebildet. Ein neuer MA-Komplex wurde im Uranyl-Glutaminsaeure-System gefunden. Eine graphische Behandlung der spektralen Daten im sichtbaren Bereich ergab die molaren Absorptionskoeffizienten fuer die MA- und MHA-Komplexe. (orig.)Additional details
