摘要：

The effective capacitance of an aqueous solution containing the nanoscale uranyl peroxide cage cluster U60 (Li48K12[UO2(O2)(OH)]60(H2O)n, n ≈ 310) was measured using cyclic voltammetry. The potential window (50–90 mV) for the measurements precluded changes to the oxidation state of U(VI) in the system. The effective capacitance for solutions containing 0.5–14.0 g L−1 U60 exhibited a dependence on cluster concentration caused by the dissociation of Li+ and K+ counterions from the clusters. The effective capacitance of U60 cluster solutions and salt solutions of KCl and LiCl were compared.
