过渡金属离子对高铁酸盐溶液稳定性的影响

The effect of transition metal ions on the stability of ferrate in solution

将Zn2+、Al3+等阳离子和石墨、MnO2、活性炭等固态物质分别加入到高铁酸盐溶液中,发现Zn2+、石墨等对FeO42-有稳定作用,Ni2+、Co2+、MnO2和活性炭等对FeO42-则有强烈加速分解作用。所得结果为高铁酸盐电池材料的选取和电解法制备高铁酸盐条件的优化提供了有益的实验依据。

Adding separately Zn^(2+),Al^(3+) metal ions and graphite,MnO_2, activated carbon solid state materials into ferrate solution.Zn^(2+), graphite had stabilization for FeO_4^(2-).Ni^(2+),Co^(2+),MnO_2 and activated carbon had strong acceleration for decomposition of FeO_4^(2-).These results offered the helpful experiment basis for the selection of materials of ferrate battery and the optimization of preparation conditions of ferrate by electrolytic method.
