碘化铷制备

主要通过碳酸铷与纯氢碘酸反应或Rb2SO4和相当量Ba(OH)2作用，再用HI中和生成的RbOH，至无碱性反应。

为了得到碳酸铷纯品，将纯RbCl加过量草酸，在铂皿中强热，转变成碳酸盐。将此残渣溶于HI中，蒸发溶液至干，熔体应不显碱性。

A study of the hydration of the alkali metal ions in aqueous solution.

Inorg. Chem. 51 , 425-38, (2012)

The hydration of the alkali metal ions in aqueous solution has been studied by large angle X-ray scattering (LAXS) and double difference infrared spectroscopy (DDIR). The structures of the dimethyl su...

Correlated ionic hopping processes in crystalline and glassy electrolytes resulting in MIGRATION-type and nearly-constant-loss-type conductivities.

Phys. Chem. Chem. Phys. 7(1) , 157-65, (2005)

Solid electrolytes with disordered structures may be crystalline or glassy. Their complex ionic conductivity displays a characteristic frequency dependence. Modelling the dynamics of the mobile ions, ...
