Embodiment 1 2
[0016] The preparation of embodiment 1 ferrous iron supply liquid
[0017] Put citric acid monohydrate powder (2.5mol) with a purity of ≥99% into a reactor with 10L of water, heat up to 60°C, and slowly add a total of 3mol of carbonic acid with a purity of ≥97% in 10 batches under stirring. Sodium, stir for 6 minutes after each batch is added and heat up to 80°C, use nitrogen to isolate the air, add 1 mol of ferrous sulfate heptahydrate with a purity of ≥95% at one time, finally heat up to 92°C, and keep stirring at 92°C to react 2 hours. Cool down to room temperature in the absence of air. Finally, a ferrous iron supply liquid is obtained.
[0018] After inspection, in the ferrous iron supply liquid of the present embodiment, the total concentration of ferrous ions (ferrous iron) in the mixed solution is 0.095mol / L, and the moles of ferrous sodium citrate, ferrous sulfate, and ferrous citrate The mass ratio is 1:0.28:0.23.
Embodiment 2 2
[0019] Embodiment 2 Preparation of ferrous iron supply liquid
[0020] Put citric acid monohydrate powder (2.5mol) with a purity of ≥99% into a reactor with 10L of water, heat up to 50°C, and slowly add a total of 3mol of carbonic acid with a purity of ≥97% in 8 batches under stirring. Sodium, after each batch is added, stir for 8 minutes and heat up to 70°C, use nitrogen to isolate the air, add 1 mol of ferrous sulfate heptahydrate with a purity of ≥95% at one time, finally heat up to 88°C, and keep stirring at 88°C for 5 Hour. Cool down to room temperature in the absence of air. Finally, a ferrous iron supply liquid is obtained.
[0021] After inspection, in the ferrous iron supply liquid of the present embodiment, the total concentration of ferrous ions (ferrous iron) in the mixed solution is 0.095mol / L, and the moles of ferrous sodium citrate, ferrous sulfate, and ferrous citrate The mass ratio is 1:0.38:0.17.
Embodiment 3 2
[0022] Embodiment 3 Preparation of ferrous iron supply liquid
[0023] Put citric acid monohydrate powder (2.5mol) with a purity of ≥99% into a reaction kettle with 10L of water, raise the temperature to 55°C, and slowly add a total of 3mol of sodium carbonate with a purity of ≥97% in 12 batches under stirring After each batch is added, stir for 4 minutes and raise the temperature to 75°C, use nitrogen to isolate the air, add 1 mol of ferrous sulfate heptahydrate with a purity of ≥95% at one time, and finally raise the temperature to 90°C, and keep stirring at 90°C for 2 Hour. Cool down to room temperature in the absence of air. Finally, a ferrous iron supply liquid is obtained.
[0024] After inspection, in the ferrous iron supply liquid of the present embodiment, the total concentration of ferrous ions (ferrous iron) in the mixed solution is 0.095mol / L, and the moles of ferrous sodium citrate, ferrous sulfate, and ferrous citrate The mass ratio is: 1:0.35:0.2.
