研究了温度、pH、醋酸钠、Fe(Ⅲ)、氯化钠等对K2FeO4水溶液稳定性的影响。随着温度的升高,K2FeO4在酸性介质中的稳定性逐渐减弱,随pH的增大,K2FeO4的稳定性逐渐增强;在中性介质中醋酸钠能够增强K2FeO4的稳定性,而在酸性介质中,却能够加速K2FeO4的分解;在中性和酸性介质中,三价铁盐的存在能够加速K2FeO4的分解;氯化钠能增强K2FeO4的稳定性。
The effects of temperature, pH, sodium acetate, Fe (Ⅲ) and sodium chloride on the stability of K2FeO4 aqueous solution were studied. With the increase of temperature, the stability of K2FeO4 in acid medium gradually weakened, with the increase of pH, K2FeO4 stability gradually increased; sodium acetate in neutral medium can enhance the stability of K2FeO4, while in acidic medium , But can accelerate the decomposition of K2FeO4; In neutral and acidic medium, the presence of ferric salts can accelerate the decomposition of K2FeO4; Sodium chloride can enhance the stability of K2FeO4.
