Embodiment 2
[0044] A. 11g of manganese sulfate was dissolved in 80ml of distilled water to obtain an aqueous manganese sulfate solution with a concentration of 0.14g / ml; 0.5g of polyethylene glycol was dissolved in 30ml of distilled water to obtain a concentration of 0.016g / ml of polyethylene glycol Ethylene glycol aqueous solution; 12g potassium permanganate and 40g ferric nitrate are dissolved in 100ml of distilled water to make a mixed solution, wherein the concentration of potassium permanganate is 0.12g / ml, and the concentration of ferric nitrate is 0.4g / ml;
[0045] B. Place each solution in step A at 30°C and stir evenly at a speed of 80 rpm;
[0046] C. At 30°C, add the polyethylene glycol aqueous solution that has been uniformly stirred in step B to the manganese sulfate aqueous solution, and after uniform stirring at a speed of 80 rpm, add a mixed solution of potassium permanganate and ferric nitrate to it, Make the mol ratio of the sum of the manganese ion in the potassium p...
