Embodiment 1
[0047] The composition and mass percentage of electrolytic manganese slag are: SO 3 32.26%, SiO 2 26.32%, CaO 21.65%, Al 2 O 3 5.96% Fe 2 O 3 6.52%, MnO 2.61%, K 2 O 1.98%, MgO 1.67%, Na 2 O 0.521%, others 0.509%. The electrolytic manganese slag was dried at 70°C for 10 hours, then ground in a ball mill with a rotational speed of 2600 r / min for 1 min, and then the ground product was passed through a 200-mesh sieve to obtain electrolytic manganese slag particles;
[0048] Mix 10g of electrolytic manganese residue particles with 60g of hydrochloric acid solution with a mass concentration of 10% at 70°C for 100min, and filter to obtain filter residue;
[0049] 5g of filter residue and 2.5g of sodium hydroxide were calcined at 500°C for 1h, and then ground into flour-like powder with a mortar;
[0050] Stir and mix 3g of powder and 18g of distilled water at 30°C to convert the powder into soluble matter and dissolve it into the liquid phase. Afterwards, use silicon mol...

[0053] The composition and mass percentage of electrolytic manganese slag are: SO 3 32.83%, SiO 2 25.9%, CaO 21.17%, Al 2 O 3 6.10% Fe 2 O 3 6.78%, MnO 2.69%, K 2 O 1.94%, MgO 1.56%, Na 2 O 0.588%, others 0.442%. The electrolytic manganese slag was dried at 80°C for 12 hours, then ground in a ball mill with a rotational speed of 2800 r / min for 2 min, and then the ground product was passed through a 300-mesh sieve to obtain electrolytic manganese slag particles;
[0054] Mix 6g of electrolytic manganese slag particles with 42g of sulfuric acid solution with a mass concentration of 10% at 80°C for 120min, and filter to obtain filter residue;
[0055] 4g of filter residue and 4.8g of sodium hydroxide were roasted at 800°C for 2h, and then ground into flour-like powder with a mortar;
[0056] Stir and mix 3g of powder and 36g of distilled water at 80°C to convert the powder into soluble matter and dissolve it into the liquid phase, and then use silicon molybdenum blue s...

[0059] The composition and mass percentage of electrolytic manganese slag are: SO 3 33.12%, SiO 2 24.86%, CaO 21.03%, Al 2 O 3 6.19% Fe 2 O 3 6.91%, MnO 2.67%, K 2 O 2.16%, MgO 1.69%, Na 2 O 0.578%, others 0.792%. The electrolytic manganese slag was dried at 90°C for 14 hours, then ground in a ball mill with a rotational speed of 3000 r / min for 3 min, and then the ground product was passed through a 400-mesh sieve to obtain electrolytic manganese slag particles;
[0060] Mix 8g of electrolytic manganese slag particles with 64g of sulfuric acid solution with a mass concentration of 15% at 90°C for 140min, and filter to obtain filter residue;
[0061] 20g filter residue and 30g sodium hydroxide were roasted at 900°C for 3h, and then ground into flour-like powder with a mortar;
[0062] Stir and mix 10g powder and 140g distilled water at 60°C to convert the powder into soluble matter and dissolve it into the liquid phase, then use silicon molybdenum blue spectrophotom...
