Abstract
The behavior of ruthenium tetroxide in solutions of oxalic, citric, and tartaric acid was investigated. Absorption spectra at 250 to 700 m mu polarographic halfwave potentials, and diffusion coefficients are presented. In addition, electrophoretic mobilities of ruthenium ions in solutions of oxalic, citric, and tartaric acid were investigated, as well as adsorption of ruthenium complexes on an ion exchanger at equilibrium conditions from solutions of various concentrations of organic acids. Spectrophotometric, polarographic, electrophoretic, and ion exchange results are compared, and the behavior of the ruthenium complexes in the various organic acids is discussed. (auth)
