摘　　要：将20种阴离子和11种阳离子分别加于pH=13、浓度为1.6×10-3mol/L的高铁酸盐溶液,发现IO4-、SiO32-、Li+、Ti4+等对溶液中的FeO42-有稳定作用;IO3-、ClO4-、Sn2+、Ba2+等对溶液中的FeO42-的稳定具有破坏作用.这一结果有助于提高高铁酸盐的稳定性,并对高铁酸盐正极材料的组成和添加剂的选取提供了实验依据.After the 20 kinds of anions and 11 kinds of cations are put into ferrate solution in which pH= 13,c= 1.6 × 10^-3 mol/L, respectively, it is found that IO4 , SiO3^2 , Li^1 , Ti^4＋ have stabilization for FeO4^2- ,but IO3^-, ClO4^-, Sn^2＋, Ba^2＋ have destruction for FeO4^2-. These results provide a direction for resolving the ferrate＇s unstability, and offer the experimental basis for the selection of materials of ferrate battery and additives.
