Laboratory method: Ferrous carbonate is often prepared by reacting alkali metal carbonate with ferrous salt solution. Hydrothermal method [2]: 0.002 mol FeSO4·7H2O and 0.010 mol urea are dissolved in 40 ml of deionized water and then transferred to a 50 ml polytetrafluoroethylene-lined stainless steel reactor and reacted at 160 °C for 4 h. The product was washed multiple times with deionized water and anhydrous ethanol, and finally dried at 60 °C for 12 h to obtain FeCO3
Waste acid method [3]: The waste acid obtained from the production of titanium dioxide by the sulfuric acid method was mixed with excess ferrous hydroxide to generate ferrous sulfate; the reaction solution was filtered to obtain a filtrate mainly containing ferrous sulfate; excess ammonium carbonate was added to the filtrate mainly containing ferrous sulfate to react, and ferrous carbonate was obtained by filtration.

§ 184.1307b(a) Ferrous carbonate (iron(II)carbonate, FeC03) is an odorless, white solid prepared by treating solutions of iron (II) salts with alkali carbonate salts. This substance is insoluble in water, but soluble in dilute acids.
