- 中文摘要: Uranyl perchlorate in aqueous solution containing α-hydroxy-iso-butyric acid (HA) and sodium perchlorate was observed at varying pH's. Two reduction waves with half-wave potentials at -0.22 and -0.95 volts vs. S. C. E., observed at pH below 3.0, are attributable to the polarographic reductions, UO2+++e→UO2+ and UO+++e→UO+, or UOOH++e UOOH, while the first wave observed above pH 3.0 or in large excess of HA above pH2.0, may be attributable to the reduction of UO2A+ complex and the third wave at -1.2 volt vs. S. C. E. to that of UOA+ complex or its dimer. A confirmation for the latter was made by polarographic reduction of uranous sulfate in HA and NaCLO4 solution.
