| 摘 要： | 在一定浓度的NaOH溶液中添加适量的Kl，KCl，KBr，用分光光度法考察此体系中FeO4^2-浓度变化。结果表明，在低浓度的碱液中加入适量的KI可以提高K2FeO4的稳定性，K2FeO4合成过程中投加KI可使K2FeO4产量和纯度都有一定的提高。KCl，KBr对NaOH溶液中K2FeO4的稳定性无明显影响。

| Abstract: | The concentration changes of (FeO_4)~(2-) in the system,which is prepared by adding KI,KCl,and KBr into NaOH solution with a certain concentration,were investigated by spectrophotometry.The results showed that the stability of K_2FeO_4 could be increased when KI was added in low concentration alkali liquor.The output and purity of K_2FeO_4 could be promoted to a certain extent when KI was added in the synthesis process of K_2FeO_4.While the KCl,KBr had no effect on the stability of K_2FeO_4 in NaOH solution. |
