Optical Absorption, Stability and Structure of NpO2+Complexes with Dicarboxylic Acids

Abstract

AbstractComplexation of NpO2+with oxalic acid (OX), 2,2'-oxydiacetic acid (ODA), 2,2'-iminodiacetic acid (IDA) and 2,2'-thiodiacetic acid (TDA), has been studied using spectrophotometry in 1 M NaClO4. Both the position and the intensity of the absorption band of NpO2+at 980 nm are affected by the formation of NpO2+/dicarboxylate complexes, providing useful information on the complexation strength, the coordination mode and the structure of the complexes.
