| 摘 要： | 采用重铬酸钾法,对酸性介质中硫酸亚铁、硫酸亚铁铵溶液中二价铁离子含量进行了测定,通过计算得出二价铁离子被氧化的损耗量,研究了不同pH值条件下的二价铁离子被氧化的损耗量,做出了量化曲线,发现在pH=3.5～5.5时,其氧化程度是相对稳定的,且硫酸亚铁铵比硫酸亚铁要稳定一些。

| Abstract: | Ferrous ion content of ferrous sulfate and ammonium ferrous sulfate solution in the acid medium was determined by using potassium dichromate method.Then,the loss amount of the divalent iron oxidation in different pH value was obtained by calculation and a quantitative curve was mde.In the pH = 3.5～5.5,its degree of oxidation was relatively stable and ammonium ferrous sulfate was more stable than ferrous sulfate. |
