| 摘 要： | 研究了在pH=9.40的碱性缓冲水溶液中,K2FeO4初始浓度、温度以及不同介质对42-稳定性的影响.结果表明,随K2FeO4初始浓度和温度升高,FeO42-稳定性下降;Fe3+使FeO42-稳定性迅速下降,且加入氯化铁的FeO42-比加入硝酸铁的FeO42-稳定;磷酸钠和草酸钠使FeO42-的稳定性降低,而氯化钾、氯化钠、醋酸钠能不同程度地增强FeO42-的稳定性,其中氯化钾的效果最好.

| Abstract: | The effects of initial concentration of K2FeO4,temperature and different mediums on stability of FeO 2-4 in the alkaline buffer solution(pH=9.40)were investigated. The results showed that the stability of FeO 2-4 in the alkaline buffer solution decreases with the initial concentration of K2FeO4 or temperature increasing; Fe 3+ can make the stability of FeO 2-4 turn bad greatly,and the stability of FeO 2-4 with FeCl3 is better than that with Fe(NO3)3; sodium oxalate and sodium phosphate will accelerate decom... |
