摘要
研究了在碱性(pH值为9.40)水溶液中,K2FeO4初始浓度、温度以及加入其它不同盐类对FeO24-稳定性的影响。结果表明,随着K2FeO4初始浓度和温度的升高,FeO42-稳定性下降。Fe3+能促使FeO42-快速分解,使其稳定性迅速降低,但加入氯化铁的FeO42-比加入硝酸铁的FeO24-稳定。氯化钾、氯化钠、醋酸钠能不同程度地增强FeO24-的稳定性,其中氯化钾的效果最好。
The effects of the initial concentration of KeFeO4, temperature and various types of salt on the stability of K2FeO4 in the basic aqueous solution（pH = 9. 40）were studied respectively. Results showed that with the increase of temperature and the initial concentration of K2FeO4, the stability of K2FeO4 in basic solution decreased. The presence of Fe3＋ ions in the solution had significant negative influence on the stability of K2FeO4, and the negative effect of ferric nitrate was serious than that of ferric chloride. Potassium chloride, sodium chloride and sodium acetate could enhance the stability of Ke FeO4 in basic solution,among them the effect of potassium chloride was the best.
