摘要
以饱和甘汞电极作参比电极 ,铂电极作指示电极组成原电池 ,通过控制原电池的电动势使混合溶液中Fe3+ 与Fe2 + 浓度之比为 2 ,再将该混合溶液加入到过量的氨水溶液中制得Fe3O4。产品用XRD。
The primary cell reported in this paper was composed of saturated calomel electrode and platinum electrode, used as reference and indicator electrode respectively. Through controlling the electromotive force of the primary cell, the ratio of Fe 3+ and Fe 2+ concentration in the mixed solution could be fixed at 2. After adding this mixed solution to excessive ammonia solution, Fe 3O 4 formed and was characterized by XRD and IR methods.
